Temperaturabhängige Steuerung: Shelly 1PM Mini und Wemos D1 Mini kombinieren

In diesem Beitrag möchte ich dir ausführlich erläutern, wie du eine Temperaturabhängige Steuerung mit einem Shelly Mini und einem Wemos D1 Mini aufbaust. Die neuen Shelly Minis haben leider keine Schnittstelle für ein Addon wo man sonst Sensoren anschließen und über die Shelly Smart Control App auslesen und in eine intelligente Szene einbauen kann. https://youtu.be/eXSIISVeN1Y

Warum benötigt man einen extra Mikrocontroller?

Die Shelly Minis sind derzeit in der dritten Generation (Gen3) erhältlich und mitunter genauso leistungsstark wie die großen Shelly Plus Geräte. Das Einzige, was denen fehlt, ist eine Schnittstelle für ein Addon an welches wir Sensoren anschließen können. Wollen wir jedoch Sensorabhängig eine Szene oder das Relais aktivieren, so benötigen wir eine externe Quelle.

Warum wird der Wemos D1 Mini eingesetzt?

Der Wemos D1 Mini ist ein kleiner ESP8266, welcher recht günstig erhältlich ist und vor allem, was ich besonders cool finde, kann auf diesen Mikrocontroller Sensoren und Aktoren gesteckt werden.

Wemos D1 Mini mit OLED Display & DHT22 Sensor

Wemos D1 Mini mit OLED Display & SHT30 Sensor

Shields für den Wemos D1 Mini Für den Wemos D1 Mini gibt es das Shield mit einem DS18B20, SHT30, DHT11 und DHT22 Sensor. Für diesen Beitrag verwende ich den Sensor SHT30. Das DS18B20 Sensor Shield ist am digitalen Pin D2 angeschlossen, an diesem liegt jedoch auch die I2C Schnittstelle an und diese benötigen wir für das OLED Display somit fällt dieses hier raus. Erhältliche Varianten des Wemos D1 Mini Den kleinen Mikrocontroller Wemos D1 Mini erhältst du derzeit in der Version 4.0 mit einem ESP8266. Wenn du jedoch mehr Leistung (CPU, Speicher) benötigst, dann kannst du auch auf eine Variante mit einem ESP32-S2 zurückgreifen. Beide Varianten kannst du für dieses Projekt verwenden!

Wemos D1 Mini - Varianten Die beiden gezeigten Mikrocontroller habe ich dir bereits in separaten Beiträgen vorgestellt und einige Schaltungen präsentiert. - Vorstellung – Wemos D1 Mini V4 - Lolin S2 mini V1 im Test Technische Daten des Wemos D1 Mini Hier nun die technischen Daten des Wemos D1 Mini V4: Wemos D1 Mini V4Taktgeschwindigkeit80 / 160 MHzBetriebsspannung3.3 VAnzahl digitale Pins11Anzahl analoge Pins1Speicher4 MB SchnittstellenI²C, SPI, UARTUSB-AnschlussUSB-Typ-CVergleich der technischen Daten vom Wemos D1 Mini V4 & V3

Wie werden die Geräte miteinander interagieren?

Der Shelly verfügt über ein Relais, mit welchem man einen Verbraucher schalten kann. Der Shelly 1PM Mini Gen3 hat den Vorteil, dass dieser noch zusätzlich die Leistungsaufnahme messen kann. Mit dem Wemos D1 Mini wollen wir temperaturabhängig das Relais aktivieren / deaktivieren und auf dem OLED Display den Zustand anzeigen. Zusätzlich können wir auch die momentane Leistungsaufnahme anzeigen.

Der Vorteil dieser Schaltung liegt in ihrer einfachen Erweiterbarkeit. Zum Beispiel kannst du einen zusätzlichen Taster einbauen, um das Relais manuell ein- und auszuschalten, oder andere Sensoren integrieren. Mit einem IR Shield und der passenden Fernbedienung könntest du zudem weitere Geräte steuern und dir so ein kleines, intelligentes Dashboard schaffen.

Benötigte Ressourcen für dieses kleine Projekt

Schauen wir uns zunächst an, welche Ressourcen benötigt werden, um das kleine Projekt umzusetzen: - einen Shelly Mini - Shelly 1 Mini Gen* - Shelly 1PM Mini Gen3* - einen Wemos D1 Mini V4* - ein USB-C Datenkabel* - ein SHT30 Shield* - ein OLED Shield* - eine Dual Base Plate*

Shelly 1PM Mini Gen3 & Wemos D1 Mini Alternativ kannst du auch das Shield mit einem DHT11/DHT22 Sensor* verwenden. Hinweis von mir: Die mit einem Sternchen (*) markierten Links sind Affiliate-Links. Wenn du über diese Links einkaufst, erhalte ich eine kleine Provision, die dazu beiträgt, diesen Blog zu unterstützen. Der Preis für dich bleibt dabei unverändert. Vielen Dank für deine Unterstützung! Für den Shelly 1PM Mini Gen3 benötigst du noch ein Anschlusskabel, hier kommt es auf den Einsatzzweck an, in meinem Fall verwende ich ein 3x1,5mm² flexibles Kabel mit einem Schukostecker.

Programmieren des Wemos D1 Mini

Den Shelly habe ich bereits mit der Cloud verbunden und damit Zugriff auf die Verbrauchsdaten und dem Relais. In diesem Abschnitt möchte ich dir gerne zeigen, wie der Wemos D1 Mini programmiert werden muss um das Relais zu steuern & die Verbrauchsdaten anzuzeigen. Programm - Temperaturabhängige Steuerung eines Shelly Minis mit dem Wemos D1 Mini & SHT30 SensorHerunterladen Schritt 1 - steuern des Relais via Postman Mit dem Tool Postman kann man Requests an Services senden und eine Antwort auswerten. Dabei kann der Request mit allen benötigten Informationen (Header, Body, Parameter etc.) bestückt werden. Das gute ist, dass man dazu erst einmal nichts programmieren muss, sondern man kann zunächst die URL und die benötigten Eigenschaften des Requests ermitteln. //aktivieren des Relais http://192.168.178.141/rpc/Switch.Set?id=0&on=true //deaktivieren des Relais http://192.168.178.141/rpc/Switch.Set?id=0&on=false In der offiziellen, englischen Dokumentation zur Schnittstelle von Shelly findest du alle Informationen, welche Daten du abgreifen kannst. Schritt 2 - Auslesen der momentanen Leistungsaufnahme am Shelly 1PM Mini Gen3 via Postman Wenn du wie ich den Shelly 1PM Mini Gen3 verwendest, dann kannst du vom angeschlossenen Verbraucher noch zusätzlich Daten ermitteln. Du kannst neben dem aktuellen Energieverbrauch in Watt, die Stromaufnahme in Ampere ermitteln. Vom Stromnetz selber können wir die Spannung und die Netzfrequenz ermitteln. http://192.168.178.141/rpc/Switch.GetStatus?id=0

JSON Output von der Shelly API Schritt 3 - Auslesen der Daten am Wemos D1 Mini In der Arduino IDE kannst du dir Daten auf dem seriellen Monitor ausgeben lassen, das hat den Vorteil das wir nicht immer zwingend ein Display benötigen. Auf der seriellen Schnittstelle wollen wir zunächst die ermittelten Daten ausgeben. Schritt 3.1 - Aufbau einer WiFi-Verbindung Bevor wir etwas auslesen können, müssen wir eine WiFi-Verbindung zum lokalen Netzwerk herstellen. #include WiFiServer server(80); //Die Zugangsdaten zum WiFi-Netzwerk const char *ssid = "xxx"; const char *password = "xxx"; void initWifiModul() { Serial.println("Aufbau der Verbindung zu: " + String(ssid)); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); } Serial.println(); Serial.println("Mit " + String(ssid) + " erfolgreich verbunden!"); server.begin(); Serial.println("Server gestartet"); Serial.print("Adresse : http://"); Serial.println(WiFi.localIP()); } void setup() { Serial.begin(9600); initWifiModul(); } void loop() { // put your main code here, to run repeatedly: } Auf der seriellen Schnittstelle wird bei erfolg die IP-Adresse des Wemos ausgegeben. (Für diesen Beitrag nicht relevant.) Aufbau der Verbindung zu: FRITZBox7590GI24 ....... Mit FRITZBox7590GI24 erfolgreich verbunden! Server gestartet Adresse : http://192.168.178.68 Schritt 3.2 - Absenden eines HTTP-Request an den Shelly Zum Absenden der Daten benötigen wir einen HTTPClient, natürlich senden wir diesen Request nur ab wenn die WiFi-Verbindung besteht! #include String shellyServerAdress = "http://192.168.178.141/rpc/"; String shellyGetStatus = "Switch.GetStatus?id=0"; void sendHttpRequest(String url) { if (WiFi.status() == WL_CONNECTED) { WiFiClient client; HTTPClient http; http.begin(client, url.c_str()); int httpResponseCode = http.GET(); Serial.print("HTTP Status Code: "); Serial.println(httpResponseCode); String payload = http.getString(); Serial.println(payload); http.end(); } } Auf der seriellen Schnittstelle sehen wir nun neben dem Antwortcode vom Shelly (HTTP Status Code) noch zusätzlich den JSON Respond mit den gewünschten Daten.

Ausgabe der Daten eines Shelly 1PM Mini Gen3 auf dem seriellen Monitor Schritt 3.3 - Parsen des JSON Respond Um an die Daten im JSON Respond vom Shelly zu gelangen, müssen wir diesen jetzt parsen. Dafür benötigen wir die Bibliothek ArduinoJson. #include StaticJsonDocument json; char jsonResponse = ""; String relais = ""; String energieverbrauch = ""; String stromaufnahme = ""; String spannung = ""; String frequenz = ""; bool sendHttpRequest(String url) { if (WiFi.status() == WL_CONNECTED) { WiFiClient client; HTTPClient http; http.begin(client, url.c_str()); int httpResponseCode = http.GET(); Serial.print("HTTP Status Code: "); Serial.println(httpResponseCode); String payload = http.getString(); Serial.println(payload); payload.toCharArray(jsonResponse, sizeof(jsonResponse)); http.end(); return httpResponseCode == 200; } return false; } void printData(String text, String value, int index) { Serial.print(text); Serial.println(value); } void readData() { if (sendHttpRequest(shellyServerAdress + shellyGetStatus)) { DeserializationError error = deserializeJson(json, jsonResponse); if (error) { Serial.print(F("deserializeJson() failed: ")); Serial.println(error.f_str()); return; } Serial.println(); energieverbrauch = json + " W"; stromaufnahme = json + " A"; spannung = json + " V"; frequenz = json + " Hz"; relais = json == true ? "AN" : "AUS"; printData("Relais: ", relais, 0); printData("Energieverbrauch: ", energieverbrauch, 1); printData("Stromaufnahme: ", stromaufnahme, 2); printData("Spannung: ", spannung, 3); printData("Frequenz: ", frequenz, 4); } } Die Antwort vom Shelly (im JSON-Format) haben wir nun im Zugriff und können dort recht einfach auf die Daten zugreifen. Aufbau der Verbindung zu: FRITZBox7590GI24 ....... Mit FRITZBox7590GI24 erfolgreich verbunden! Server gestartet Adresse : http://192.168.178.68 HTTP Status Code: 200 {"id":0, "source":"switch", "output":true, "apower":14.5, "voltage":227.5, "freq":50.0, "current":0.112, "aenergy":{"total":2.884,"by_minute":,"minute_ts":1716113335}, "ret_aenergy":{"total":0.000,"by_minute":,"minute_ts":1716113335},"temperature":{"tC":55.5, "tF":131.9}} {"id":0, "source":"switch", "output":true, "apower":14.5, "voltage":227.5, "freq":50.0, "current":0.112, "aenergy":{"total":2.884,"by_minute":,"minute_ts":1716113335}, "ret_aenergy":{"total":0.000,"by_minute":,"minute_ts":1716113335},"temperature":{"tC":55.5, "tF":131.9}} Energieverbrauch: 14.500 W Stromaufnahme: 0.112 A Spannung: 227.500 V Frequenz: 50.000 Hz Schritt 4 - Anzeigen der Daten auf einem OLED Display Da wir die Daten vom Shelly nun ausgelesen haben, möchte ich dir zeigen wie diese auf einem OLED Display angezeigt werden. Für das ansteuern des OLED Displays am Wemos D1 Mini gibt es eine extra Bibliothek von Adafruit welche du bequem über den Bibliotheksverwalter installieren kannst.

Bibliothek für das kleine OLED Display von Wemos Die Adresse des OLED Displays ist 0x3c, mit dem kleinen Programm aus dem Beitrag Arduino I2C-Scanner für ESP8266 & ESP32 anpassen: Eine Schritt-für-Schritt-Anleitung kannst du am ESP8266 nach geräten suchen. An LOLIN(WEMOS) D1 mini Pro was recognized! The microcontroller has 1 I2C Interfaces! SDA: 4, SCL: 5 Scanning... I2C device found at address 0x3c! End. Ich würde dir empfehlen eine zuvor installierte Version der Adafruit_SSD1306 zu deinstallieren damit eventuelle Probleme minimiert werden. #include #include #include #include #define OLED_RESET 0 // GPIO0 Adafruit_SSD1306 display(OLED_RESET); void setup() { Serial.begin(9600); initWifiModul(); display.begin(SSD1306_SWITCHCAPVCC, 0x3C); display.setTextSize(1); display.setTextColor(WHITE); } void printData(String text, String value, int index) { Serial.print(text); Serial.println(value); display.setCursor(0, index * 10); display.println(value); } void loop() { display.clearDisplay(); readData(); display.display(); delay(2000); } Die Daten werden nun nicht nur auf der seriellen Schnittstelle ausgegeben sondern auch auf dem OLED Display. Da das Display sehr klein ist, kann hier keine zusätzliche Bezeichnung hinzugefügt werden und es werden lediglich die Werte angezeigt.

Daten eines Shellys (deaktiviert)

Daten eines Shellys (aktiviert) Schritt 5 - Auslesen des Temperatursensors SHT30 Wie eigentlich ganz am Anfang erläutert soll das Relais temperaturabhängig gesteuert werden, dazu stecken wir nun das SHT30 Shield auf den freien Platz der Dual Base Plate.

Wemos D1 Mini mit OLED Display & SHT30 Sensor Man könnte auch die die Shields untereinander auf einem Breadboard stecken. Jedoch strahlt jedes elektrische Gerät eine wärme ab wie auch der WiFi Chip des Wemos D1 Mini und wenn der Sensor zu nah an diesem ist, werden die Werte stark beeinflußt. Technische Daten des SHT30 Sensors Den SHT30 Sensor habe ich dir bereits im Beitrag Wemos D1 mini Shield: SHT30 Temperatur und Luftfeuchtigkeit Sensor vorgestellt und gezeigt wie dieser programmiert wird. Hier nun die technischen Daten Sensors: - Betriebsspannung: 3V bis 5,5V DC - Betriebstemperatur -40 °C bis 125 °C - Schnittstelle: I2C (0x44 Standard / 0x45 über Lötpunkte) - Temperatur: -40 bis +125 °C (± 0,3 °C) - relative Luftfeuchtigkeit : 0 % bis 100 % (± 2 %) Bibliothek zum auslesen des Sensors Für den Sensor gibt es von Wemos eine Bibliothek welche du dir Read the full article

Let me introduce my current main WIP. It's not fandom related, it's for my model railroad, and it's not yet finished.

This is a rendering of a circuit board that I'm designing at the moment. It will be a DCC command station. My model railroad is run digitally, which means the tracks carry digital signals that tell each locomotive and switch individually how to run, which lights to turn and so on. The command station is the device that generates that. I have a number of different layouts, one of which has a good command station, one of which has a crappy old one, and the final one isn't even digital yet. So this will be the one that solves all issues for me, hopefully.

The design above isn't finished yet, and even the parts that are are not yet fully representative. The different capacitors are just there as options; some screen print overlaps; and some components (in particular all plugs and the relays that control the programming track) don't have 3D models so they don't show up.

Planned features:

Four layer board

10-25 V DC output, software controllable

Up to 5A output power, limited mainly by the main switching regulator.

Input 15-25V either AC or DC with polarity protection, selectable with some solder bridges (not yet in there). Optionally you can also bypass the main power regulator with another solder bridge (that I haven't added yet); useful in case you use e.g. a laptop power supply with a switchable voltage and don't need any regulation after that.

Railcom support

USB connection; not yet sure what for, but the main chip I'm using has USB support and I have some spare USB connectors here, so in it goes.

Speaking: The chip is an STM32L433RCT6P, chosen because I found it in stock at an electronics distributor. 64 kB RAM, 256 kB EEPROM, with support for an additional up to 256 MB externally (there's a spot for that on the board) and lots of fun extras that I don't technically need. It has an FPU! I don't need an FPU, but I will definitely do some floating point math computation on it just for fun.

Main external connection is WLAN using an ESP32 WROOM U module. I haven't decided on the housing, but I may go for extruded aluminum, so it's the U version that allows and requires an external antenna

It supports XBUS/XpressNet connections for old throttles from Lenz and Roco that I should probably throw away, but I paid good money for them, dang it.

It supports CAN for LCC / OpenLCB. I may not populate this part on all boards that I'm building, because I haven't actually decided whether I am interested. But the chip has CAN functionality built in, so why not.

There's an I2C connection to connect a cheap tiny OLED display for status messages.

Test points for all important signals (in particular the different internal voltage levels; yes, there is 3.3V, A3.3V and -3.3V and I need all of them).

Stuff still to add:

I will add pin headers (or space for pin headers anyway) for all the remaining pins on the STM32, and perhaps some on the ESP32, for future expansions.

Status LED and stop/go button on the front

Wire it all up, maybe move some stuff (mostly the STM32 around), which will cause all sorts of fun new routing issues.

Adjustments to make the jacks line up with the front panel once I've decided on a housing.

Features I'm not considering adding:

s88. I vaguely know what it is but I don't have any devices like that, and if that ever changed I could probably build (or perhaps buy) a converter that connects them via CAN.

Other buses like LocoNet.

Ethernet. I don't need it and it's actually more expensive than WLAN in this day and age.

In terms of software, I'm planning to use DCC-Ex on it. The whole project actually started out as a DCC-Ex shield, but once I realised that this wouldn't fit, I decided to make it standalone. Now, DCC-Ex is designed for Arduino, not STM32, and it doesn't support XpressNet, nor OpenLCB, nor Railcom, and their Wifi protocol is pretty weird and annoying which will be an issue (I'm planning to write my own control app for iPhone for it), so I'll probably change that or just replace it with the z21 one… so really, the software will not look a lot like DCC-Ex once I'm done with it.

Will this all work? I have honestly no idea. I mean, I'm fairly confident, I'd have given up on this long ago otherwise, but I have no guarantees either way until I've spent a lot of money on components and circuit boards and start soldering. Turns out doing it this way is not really cheaper than just buying a half-way decent one. That's what makes it exciting, though!

If it does work, obviously this will be released as open source. But it's still going to be a few days (more realistically weeks) before it's even ready to order the parts, and then a lot of soldering (current BOM stands at 194 actual components), and then a lot of software development before it's ready for that.

Sensor

What are Sensors?

The sensor may be defined as a machine, module, subsystem, or device whose purpose is to detect changes and events in the environment. The information regarding these changes is further sent to various other electronics mostly comprising of a computer processor. A sensor is always used along with an electronic device.

Sensors are used in various everyday objects comprising of lamps with touch sensation which dim and light up by touching the base and touch-sensitive elevator buttons. With time, there have been advances in micromachinery and microcontroller platforms that are easy to use.

Read More

With time, the uses of sensors have increased beyond pressure or flow measurement and traditional fields of temperature. Analog sensors such as force-sensing resistors and potentiometers are widely in use even today.

The applications comprise airplanes and aerospace, medicine, cars, manufacturing and machinery, robotics, and various other aspects related to daily life. There are various sensors available that are used for measuring the physical and chemical properties of materials.

Now let’s read about the classification of sensors after which we will go through the types of sensors and how sensors work.

Classification of Sensors

Sensors are classified on the basis of the output signal, physical parameters measured by them, and various other points. Sensors on the basis of the output signal are classified into analog and digital output sensors.

The output given by the sensors in the case of analog output sensors is an analog voltage that can be measured and used for determining the required physical parameter. This is done by making use of the sensor’s transfer function. It may be resistive, capacitive, or anything which is analog.

The digital data which can be read via parallel or serial communication buses is the output of digital output sensors. The format for the data, in this case, is demonstrated in the sensor’s datasheet. An accelerometer sensor is an example of a digital sensor that is used for sending the output data by using the I2C two-wire bus.

The sensors are further classified on the basis of physical parameters; these types may be used for measuring anything. The most common sensors are tilt sensor, magnetic sensor, cameras, color sensor, pressure sensor, fingerprint sensor, current sensor, light sensor, etc.

Different Types of Sensors with Their Applications

In daily life, it has become our habit to implement various types of sensors frequently in the power systems comprising of load control systems, electrical and electronics appliances, and industrial and home automation. All types of sensors are further divided into analog and digital sensors.

However, there are few types of sensors that are used in electronic applications such as pressure sensors, touch sensors, IR sensors, ultrasonic sensors, temperature sensors, proximity sensors, and so on.

Temperature Sensors:

Temperature is the commonly measured environmental quantity for various reasons. There are different types of temperature sensors that are used for measuring temperature such as thermistors, resistance temperature detectors, thermocouples, semiconductor temperature sensors, and so on.

On the basis of requirements, various types of sensors are used for the purpose of measuring temperature in different applications. A simple temperature sensor with a circuit may be used for switching the load on and off at a specific temperature.

Read More

This temperature is detected by the temperature sensor, in these cases, a thermistor is put to use. The temperature sensor circuit comprises a thermistor, transistor, relay, and battery. The temperature sensor activates the relay by detecting the required temperature.

The relay switches on the load that is connected to it which can be AC or DC. This circuit may be further utilized for the purpose of controlling the fan on the basis of temperature. Primarily, this type of sensor may be further classified into various other types such as digital temperature sensors, thermistors, and so on.

IR Sensors:

The small photo chips comprising of photocells that are used for detecting and emitting infrared light are termed IR sensors. These sensors are most commonly used for the purpose of designing remote-control technology.

These sensors may be used for detecting various obstacles of the robotic vehicle and controlling the direction of the same. There are different types of sensors that might be used for the detection of infrared lights.

A simple example of an IR sensor circuit that we use in our day-to-day life is a TV remote control. It comprises IR receiver circuits and IR emitter circuits that may be designed. The IR emitter circuit is used as a remote by the user for the purpose of emitting infrared light.

This infrared light is transmitted or sent to the IR receiver circuit which interfaces to the devices such as IR remote-controlled robots or a TV. These sensors are further used for designing television remote controls.

A TV remote is an example of a simple IR sensor-based electronics project which is used for the purpose of controlling a robotic vehicle in remote areas by using IR or TV remote. This type of TV remote is being utilized for sending commands to the robotic vehicle.

Ultrasonic Sensor:

An ultrasonic sensor or transceiver is a transducer that works on the principle alike radar or sonar and is known for estimating the attributes of the target by interpreting. These sensors are classified as active and passive ultrasonic sensors and maybe differentiated on their working.

The active ultrasonic sensors are known for generating high-frequency sound waves that are received back by the ultrasonic sensor for the evaluation of echo. The time interval taken for receiving and transmitting the echo helps in the determination of the distance to an object.

However, the passive ultrasonic sensors are merely used for the detection of ultrasonic noise whose presence can be found in specific conditions. When it comes to the practical application of an ultrasonic sensor with a circuit, it may also be used as an ultrasonic distance sensor circuit.

Touch Sensor:

The switches that are activated by touch may be said to have touch sensors. These sensors are classified into different types on the basis of their touch-type such as piezo touch switch, capacitance touch switch, and resistance touch switch.

For the purpose of controlling the load, a touch-sensitive load is designed. The touch-controlled load switch which is touch sensor principle-based comprises various blocks such as touch sensor plate, load, relay, and power supply block.

Proximity Sensor:

The proximity sensor is a type of IoT sensor in which the existence and non-existence of the surrounding objects are identified. After this, the detected signal is converted into a form that the user understands.

This type of sensor is mainly applied in the retail domain where any movement is found out and an association is present between the consumer and product. The users are provided with quick notifications related to exclusive offers and discount updates of the products in which they are interested.

Chemical Sensor:

A chemical sensor helps in determining various kinds of changes in liquid and for detecting the air chemical variations. These are mainly put to use in bigger cities and towns as it is important to look after the changes for providing safety to the people.

This type of sensor is essentially implemented in commercially atmospheric observation. It is used for processing management which may comprise of fortuitously or intentionally evolved chemicals, radioactive exposure, pharmaceutical industries, and reusable operations in space stations.

The most commonly used chemical sensors include chemical FET, electrochemical gas type, chemi resistor, non-dispersive IR, zinc oxide nanorod, and fluorescent chloride type.

Gas Sensor:

Gas sensors are similar to chemical sensors but are specially implemented for observing modifications in the quality of air. This is done to find out which types of gases are present in it. This sensor is being used in multiple domains such as health, manufacturing, agriculture, for supervision of gas in coal industries, chemical laboratory investigations, etc.

Some of the gas sensors that have been put to use include hydrogen type, hygrometer, carbon-dioxide sensor, ozone monitoring type, air pollution type, gas detection type, etc.

Humidity Sensors:

Humidity is used for defining the vapor present in the atmosphere or in gaseous substances. Humidity sensors are used as temperature sensors as the manufacturing operations require similar operating conditions. By measuring humidity, it can be ensured that the complete procedure will pass away easily.

In case of modification, immediate action can be taken as these sensors are known for quickly identifying the variations. There are numerous domains in which these are used such as ventilators, residential and commercial use for heating purposes, etc. Some other domains include meteorology, greenhouses, automobile, painting, coating industries, and hospitals.

Acceleration Sensor:

An acceleration sensor is used for calculating the acceleration and angular values. The accelerometer is primarily used for calculating acceleration. There are two types of forces that create an impact on the accelerometer; these are static force and dynamic force.

Read More

These sensors are present in numerous configurations and their type of selection is dependent on the industry’s requirement. There are few parameters that are required to be checked before selecting the sensors such as total number of axes, bandwidth, sensitivity, type of outputs, etc.

Sound Sensor:

Sound sensors can generally be identified as the microphone devices that are used for delivering the corresponding level of voltage and sound on the basis of the sound level detection. By implementing the sound sensor, a small robot may be manufactured for navigation on the basis of sound received.

In comparison to light sensors, the design process of sound sensors is complicated. The reason being the delivery of minimal voltage difference by them. This is further to be amplified for providing voltage variation that is measurable.

Various other sensors include a light sensor, tactile sensors, force sensors, etc. The types of sensors used in building include motion detection sensors, camera sensors, gas sensors, smoke and fire detection sensors, electric voltage and current sensors, and temperature sensors.

Uses of Sensors

If we look around carefully, sensors are used in many products that we use in our day-to-day life. Sensors are used in various industries comprising automotive, medical, aerospace, defense, and agriculture.

Position sensors are used for the purpose of measuring movement, displacement, and position and maybe rotary or linear. These are used for controlling the throttle, measuring wind direction, positioning the ramp and bridge, simulating flights, and steering angle measurement.

Pressure sensors are being used for measuring pressure and can be a differential, gauge, or absolute. The most common types of pressure sensors that are used comprise transducers which are also known as pressure switches or pressure transmitters.

Some of the areas of pressure sensor application are oil pressure, tire pressure, vehicle braking systems, oil pressure, fans, filters, and diesel and engines applications. The force sensors also known as load cells or weight sensors are used for weighing applications in scales.

The weight sensors are known for giving the exact weight measurement by measuring the amount of force that is being applied. The load sensors are used in counting scales, hopper scales, platform scales, tank weighing, and on-boarding weighing.

Temperature sensors are put to use when it comes to monitoring and measuring the temperature of liquid, solid, and gas. It is the most commonly used sensor in homes and it is used in various shapes and sizes for serving different purposes.

This type of sensor is used in motors, surface plates, computers, industrial equipment, electrical radiators, exhaust gas monitoring, and home appliances. Sensors are highly beneficial and are used in various equipment used in our daily lives.

Applications of Digital Sensors

Digital sensors are the electrochemical sensors or electronic sensors in which the transmission and conversion of data take place. Digital sensors are known to have overcome the drawbacks present in analog sensors and have slowly begun to replace them.

Digital sensors are of different types such as digital accelerometers and digital temperature sensors. A digital accelerometer is known for generating variable frequency square wave output termed pulse-width modulation. In this, the readings are taken at a fixed rate by the pulse width modulated accelerometer.

A digital temperature sensor is known for providing device temperature with 9-bit temperature readings. It is known for acting as a thermostat with the presence of three thermal alarm outputs. It is being considered as a digital temperature control system that uses digital temperature sensors.

This control system has various advantages and provides accurate results in comparison to the analog temperature control system. A digital temperature control system is capable of providing a temperature display and switches off when the temperature exceeds a set point.

Real-time Application Sensor

Sensors get information from the environment and transfer it to the computer. The system transfers the input to the needed output and displays it to the user.

Civilians and military aircraft use them in one way or another. They have the AutoPilot system application where the aircraft controls its flight by itself when all the conditions are stable. This system has several sensors to measure the height, pressure, light, humidity and saves the information in the system. This information is compared with the preset information, which provides a stable condition. If both the information is the same, the computer sends information to various parts of the aircraft such as wings, rudders, stabilizers. Then the autopilot system takes control of the aircraft until found otherwise. All these are important in this system.

Another application is using the wireless network in different industries. Various sensors are used in different places to collect various data related to different fields. This data is used in medical, engineering and agricultural fields.

When the fire is detected inside the industry, the smoke detector provides a signal to the light sensor. The light sensor produces light which senses the alarm system implemented inside the industry. This produces the alarm in the industry and thus alerts security and employees.

Fitbit, the activity tracker, tracks the activities of the users by sensing the movements such as walking, running, sleeping and other motions. This helps in tracking the health of the user.

They are helpful to the people to detect smoke, to know the health, to prevent accidents. It can be used to detect a missing person as well as the presence of water on the moon.

Pros and Cons of Different Sensors

Now let’s go through the pros of different sensors. When it comes to a touch sensor, the axle hole present in the sensor area may be used for creating its own bumper. The color sensor is known for detecting color, avoiding ambient light, and following lines.

The gyro sensor can be used for accurately turning and measuring the robot turning. An infrared sensor helps in finding the beacon and remote receiver. It is known for working and helping in measuring the proximity accurately.

An ultrasonic sensor measures in and cm and provides accurate distance measurement and wall following. These were the pros of different sensors, let’s know the cons of different sensors. The con in the case of a touch sensor is that the object must touch the sensor’s red part and its sensor area is small.

Read More

The color sensor is known to be reliable only when it is at a close range and the light color that it detects is white. In the case of a gyro sensor, the robot is required to be still when it is plugged. It can be unreliable and touch many times.

The other cons of different sensors include the sound of ultrasonic which may interfere with the sensor. The infrared sensor is not allowed in FLL and is not measured in cm or in. Hope you have received a great insight regarding sensors through this blog.

Electronic Engineering Power management

New Post has been published on https://www.tuempleord.do/2020/08/14/electronic-engineering-power-management/

Electronic Engineering Power management

We need several PCBs engineered for controlling peripherals of a medical video portal, sensors and sensors breakout board. The sensors are supplied by 3rd parties.

You have engineering experience in the following fields: DC stepper motor control STM8 MCUs – UARTs, SPI, I2C, GPIO, and basic programming knowledge USB applications Embedded Systems Audio and video – Acoustic Echo Cancellation, speaker amplifiers, digital microphones, line level converters, video encoding and decoding circuitry, LVDS, HDMI, SDI and DisplayPort Power management – Solid State Relays, MOSFETs, voltage regulators PWM control for LED lighting applications Ultrasonic sensors Black burst and tri-level sync generator circuitry Enclosures prototyping Wiring harnesses Experience with mechanical engineering a plus

Most challenging is the engineering of a tri-level genlock sync generator which uses DisplayPort out of the Embedded System as reference clock. With two independently controlled MOSFETS with programmable time offset – both positive and negative – and switching duration. We need to be able to sync a screen (laser projector, LCD or OLED) and LED backlighting with a studio camera supporting tri-level sync in.

You must be able to produce small sample batches and provide assistance with the manufacturing of the electronics, electronics enclosure and wire harness on a large-scale basis.

Being familiar with FDA regulations and UL safety requirements is a major advantage.
