ArduBlock - Arduino UNO mit DHT11 & LCD-Display

In diesem Beitrag möchte ich dir erläutern, wie du die Sensordaten des DHT11 Sensors auf einem LCD-Display am Arduino UNO anzeigen lassen kannst. Die Programmierung erfolgt hier mit der grafischen Entwicklungsumgebung ArduBlock.

ArduBlock - Arduino UNO mit DHT11 & LCD-Display Die grafische Entwicklungsumgebung ArduBlock habe ich dir bereits im Beitrag Arduino IDE : Erweiterung ArduBlock vorgestellt und erste Schritte gezeigt. Dieser Beitrag ist durch einen Wunsch entstanden, den Beitrag Calliope Mini mit DHT11 & LCD-Display auf einem Arduino UNO laufen zu lassen. Die Programmierung soll dabei so einfach sein wie in MakeCode von Microsoft, daher auch die Wahl zu ArduBlock.

Benötigte Ressourcen für dieses Projekt

Wenn du die nachfolgende Schaltung aufbauen möchtest, um einen DHT11 Sensor & LCD-Display per ArduBlock am Arduino UNO programmieren möchtest, dann benötigst du: - einen Arduino UNO*, - ein USB-Datenkabel*, - einen DHT11 Sensor*, - ein LCD-Display*, - diverse Breadboardkabel*, 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! Den DHT11 Sensor erhältst du als einzelnen Baustein oder auch auf einer kleinen Platine mit einer fertigen Schaltung.

Varianten des DHT11 Sensors Ich bevorzuge die kleine Platine, da hier der Aufbau deutlich schneller vonstattengeht.

Download & Einrichten von ArduBlock

Im ersten Schritt laden wir die Anwendung ArduBlock von http://ardublock.ru/avtor/002/en.html herunter.

Wenn die ca. 300 MB große ZIP-Datei erfolgreich geladen und in ein beliebiges Verzeichnis entpackt wurde. Kann diese über die Datei ArduBlock 2.0appArduBlock.exe gestartet werden. In meinem Fall startete diese Anwendung mit russischer Sprache, hier musste ich zunächst über das Symbol "A" und dann aus der Auswahlliste die Sprache "English" wählen. Diese Auswahl muss zum schluss noch mit der Schaltfläche "OK" bestätigt werden.

Nach einem kleinen reload wird die Anwendung ArduBlock 2.0 in englischer Sprache angezeigt.

Oberfläche der Anwendung ArduBlock 2.0 Alternativ kannst du auch DUINI-EDU verwenden, welches ich dir im gleichnamigen Beitrag bereits vorgestellt habe Arduino Programmierung mit DUINO EDU.

Aufbau der Schaltung am Arduino UNO

Für den Aufbau am Arduino UNO benötigen wir lediglich den Sensor, ein LCD-Display sowie sieben Breadboardkabel.

DHT11 Temperature and Humidity Sensor

The DHT11 Digital Temperature And Humidity Sensor is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so in your code please use sensor reading interval at 2 seconds or more. Compared to the DHT22, this sensor is less precise, less accurate and works in a smaller range of temperature/humidity. But despite its disadvantages over DHT22, it is smaller and less expensive sensor for temperature and humidity measurement.

Note: This package does not include Arduino board, you have to buy it separately.

Features:

Low power consumption.

Relative humidity and temperature measurement

All calibration, digital output

Excellent long-term stability

No additional components

Long distance signal transmission

Ultra-low power

4-pin package

Completely interchangeable

MicroPython mit ESP32: DHT11 Sensordaten auslesen und verarbeiten

In diesem Beitrag erfährst du, wie man einen Umweltsensor DHT11 am ESP32 D1 R32 mit MicroPython auslesen und diese Sensordaten verarbeiten kann. Für diesen Beitrag verwende ich wieder das Rich Shield von Open Smart. Du kannst jedoch mit wenigen Bauteilen den Sensor an deinen ESP32 anschließen und dieses kleine Tutorial nachbauen. https://youtu.be/7uvoZU09s78 Der DHT11 Sensor ist eine kostengünstige und weit verbreitete Lösung zur Messung von Temperatur und Luftfeuchtigkeit. Er eignet sich hervorragend für viele DIY-Projekte, wie z.B. die Überwachung von Raumklima, Wetterstationen oder Smart-Home-Anwendungen. In den folgenden Abschnitten zeige ich dir Schritt für Schritt, wie du den Sensor anschließt, die Daten ausliest und auswertest. Zusätzlich werde ich dir zeigen, wie du die ausgelesenen Sensordaten mit einem Zeitstempel versiehst und in eine CSV-Datei speicherst. Dies ermöglicht eine einfache Weiterverarbeitung und Analyse der Daten, beispielsweise in Tabellenkalkulationsprogrammen wie Excel. So kannst du die Temperatur- und Luftfeuchtigkeitswerte über einen längeren Zeitraum überwachen und Trends erkennen.

Technische Daten des DHT11 Sensors

Mit dem DHT11 Sensor kannst du recht einfach die Temperatur und die relative Luftfeuchtigkeit messen. Dabei ist dieser Sensor nicht nur günstig, sondern auch recht genau. Wie genau dieser Sensor arbeitet, habe ich bereits im Beitrag Vergleich von Temperatursensoren für den Arduino & Raspberry PI aufgezeigt. relative LuftfeuchtigkeitMessbereich 20 % bis 90 %Toleranz±5 %TemperaturMessbereich 0 °C bis 60 °CToleranz±2 °CBetriebsspannung5V

DHT11 Sensor am Rich Shield von Open Smart

Der DHT11 Sensor ist am GPIO19 des ESP32 D12 R32 verbunden (D13 am Arduino UNO). Mit diesem Umweltsensor kannst du die Temperatur und relative Luftfeuchtigkeit messen. Dabei gibt dieser Sensor alle 1,5 Sekunden einen neuen Wert.

Aufbau der Schaltung ohne Rich Shield von Open Smart

Wenn du die kleine Schaltung ohne Rich Shield nachbauen möchtest, dann gibt es zwei Wege. Zum einen kannst du die Schaltung mit einem fertigen Baustein aufbauen und zum anderen mit dem Sensor und einem 10 kOhm Widerstand. 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! Schaltung mit einem fertigen Baustein - ein ESP32 D1 R32*, - ein Micro-USB Datenkabel*, - ein DHT11 Sensor*, - drei Breadboardkabel*, 10 cm, - ein 170 Pin Breadboard*

Bei den DHT11 & DHT22 Sensoren auf Platine musst du auf die Beschriftung achten, diese ist immer unterschiedlich. Wenn du deinen Sensor verpolst, dann kann dieser sehr schnell kaputtgehen!

Schaltung - ESP32 D1 R32 mit DHT11 Sensor als Baustein auf einer Platine Schaltung mit Sensor & Widerstand Du erhältst den Sensor auch einzeln, wenn du diesen hast, dann benötigst noch zusätzlich einen 10 kOhm Widerstand, welcher mit VCC verbunden wird. - ein ESP32 D1 R32*, - ein Micro-USB Datenkabel*, - ein DHT11 Sensor*, - ein 10 kOhm Widerstand*, - vier Breadboardkabel*, 10 cm, - ein 170 Pin Breadboard*

Schaltung - DHT11 Sensor am ESP32 D1 R32 mit Widerstand

Programmieren des DHT11 Sensors in MicroPython am ESP32 D1 R32

Damit wir den Sensor auslesen können, benötigen wir ein zusätzliches Modul. Der Firmware von MicroPython liegt bereits ein passendes DHT Modul bei, mit welchem wir den Sensor DHT11 & DHT22 mit wenigen Zeilen Code auslesen können. import dht from machine import Pin, RTC import time d = dht.DHT11(Pin(19, Pin.IN)) while True: d.measure() print("Temperatur: ", d.temperature(), "°C", sep="") print("rel. Luftfeuchtigkeit: ", d.humidity(), "%", sep="") time.sleep(2) Das kleine Programm schreibt fortwährend die Sensordaten in die Kommandozeile.

Einfache Ausgabe der Sensordaten in der Kommandozeile Ausgeben der Daten in einer Tabelle Die Daten lassen sich auch recht einfach in einer Tabelle auf der Kommandozeile ausgeben. Dazu geben wir als Erstes die Kopfzeile aus und setzen den Trenner (Parameter sep in der Funktion print) auf einen geraden Strich / Pipe. Zusätzlich hole ich mir noch den aktuellen Zeitstempel von der internen RealTimeClock. import dht from machine import Pin, RTC import time d = dht.DHT11(Pin(19, Pin.IN)) def getTimestamp(): rtc = RTC() currentDateTime = rtc.datetime() hour = currentDateTime minutes = currentDateTime seconds = currentDateTime textFormat = "{0}:{1}:{2}" if hour < 10: hour = "0"+str(hour) if minutes < 10: minutes = "0"+str(minutes) if seconds < 10: seconds = "0"+str(seconds) return textFormat.format(hour, minutes, seconds) print("Zeittt","Temperaturt", "rel. Luftfeuchtigkeit", sep="|"); while True: d.measure() print(str(getTimestamp())+"t",str(d.temperature())+"°Ctt", str(d.humidity())+"%", sep="|") time.sleep(2) Die tabellarische Ausgabe der Sensordaten auf der Kommandozeile hat den Vorteil das wir diese recht einfach ablesen können und wir könnten diese auch markieren und in eine andere Datei formatiert kopieren.

Tabellarische Ausgabe der Sensordaten auf der Kommandozeile Ausgeben in eine CSV-Datei mit Sensordaten des DHT11 auf dem ESP32 mit MicroPython Wir können auf dem Mikrocontroller auch Dateien schreiben und so die Sensorwerte aufzeichnen. Wie du Dateien schreibst werde ich dir in einem späteren Beitrag noch genauer erläutern, hier möchte ich dir der Vollständigkeitshalber ein kleines Programm zeigen, welches die Daten vom Sensor in eine CSV Datei mit dem Namen "sensordata.csv" schreibt. import dht from machine import Pin, RTC import time import os csvDatei = 'sensordata.csv' lineBreak = 'rn' dht11Sensor = dht.DHT11(Pin(19, Pin.IN)) def getTimestamp(): rtc = RTC() currentDateTime = rtc.datetime() year = currentDateTime month = currentDateTime day = currentDateTime unknown = currentDateTime hour = currentDateTime minutes = currentDateTime seconds = currentDateTime textFormat = "{0}.{1}.{2} {3}:{4}:{5}" return textFormat.format(day, month, year, hour, minutes, seconds) if not csvDatei in os.listdir(): headline = "Zeit;Temperatur;rel. Luftfeuchtigkeit"; with open(csvDatei, 'w') as f: print(headline) f.write(headline) f.write(lineBreak) while True: dht11Sensor.measure() line = str(getTimestamp())+";"+str(dht11Sensor.temperature())+";"+ str(dht11Sensor.humidity()) with open(csvDatei, 'a') as f: print(line) f.write(line) f.write(lineBreak) time.sleep(2) Der Code erstellt auf dem Mikrocontroller die Datei "sensordaten.csv" welche über das Kontextmenü (rechte Maustaste auf der Datei) heruntergeladen werden kann. Zusätzlich wird beim Ausführen des Programmes die Daten auf der Kommandozeile ausgegeben.

Thonny - MicroPython Programm zum aufzeichnen der Sensordaten in eine CSV Datei Diese CSV Datei kann recht einfach in Microsoft Excel importiert und die Daten verarbeitet und visualisiert werden.

Microsoft Excel - importierte CSV Datei

Ausblick

Die ermittelten Sensordaten könnten wir auch via HTTP Request an ThingSpeak senden und dort extern speichern und visualisieren. Wie du das machst, erläutere ich dir im nächsten Beitrag, sei also gespannt. Read the full article

Step 3: Program the Sensors

Write a Python script to read data from each sensor. Here’s a basic example for reading CO2, PM2.5, temperature, and humidity data.import time import Adafruit_DHT import board import adafruit_mq135 import adafruit_pm25

# Setup DHT_SENSOR = Adafruit_DHT.DHT22 DHT_PIN = 4 CO2_SENSOR = adafruit_mq135.MQ135(board.A0) PM25_SENSOR = adafruit_pm25.PM25_UART(board.UART1)

def read_sensors(): # Read temperature and humidity humidity, temperature = Adafruit_DHT.read_retry(DHT_SENSOR, DHT_PIN) # Read CO2 level co2_level = CO2_SENSOR.co2 # Read PM2.5 level pm25_data = PM25_SENSOR.read() pm25 = pm25_data['pm25'] if 'pm25' in pm25_data else None return temperature, humidity, co2_level, pm25

while True: temp, humidity, co2, pm25 = read_sensors() print(f"Temperature: {temp}°C, Humidity: {humidity}%, CO2 Level: {co2} ppm, PM2.5: {pm25} µg/m³") time.sleep(10)

import requests

CLOUDTOPIAA_API_KEY = "Your_Cloudtopiaa_API_Key"

def send_data_to_cloud(temp, humidity, co2, pm25): url = "https://api.cloudtopiaa.com/v1/data" # Example endpoint payload = { "temperature": temp, "humidity": humidity, "co2": co2, "pm25": pm25 } headers = { "Authorization": f"Bearer {CLOUDTOPIAA_API_KEY}" } requests.post(url, json=payload, headers=headers)

while True: temp, humidity, co2, pm25 = read_sensors() send_data_to_cloud(temp, humidity, co2, pm25) print(f"Sent data to Cloudtopiaa: Temperature: {temp}°C, Humidity: {humidity}%, CO2: {co2} ppm, PM2.5: {pm25} µg/m³") time.sleep(600) # Send data every 10 minutes

Step 5: Set Up Data Visualization

Log in to your Cloudtopiaa account to view your data in real-time. Use built-in visualization options to create charts and graphs that track air quality metrics over time.

Step 6: Build a Mobile App or Web Dashboard

Use a platform like Cloudtopiaa’s dashboard, Blynk, or a custom web interface to create a user-friendly dashboard that displays current air quality data and historical trends.
