Midiendo más de 40 cm con Arduino

Si te preguntaste alguna vez como poder utilizar esto con más de 40 cm, estás en el lugar correcto.

En mi canal de YouTube tenes el video completo con los archivos necesarios para lograrlo.

A veces con los tutoriales básicos nos alcanza pero si necesitas medir distancias mayores a 40 cm y ver el resultado en Processing podes utilizar mi acercamiento. El sensor HCSR04 puede medir un rango máximo de 400cm.

En mi caso son poco más de 300 cm efectivos, esto varía según el fabricante.

Smart trash monitoring system

SMART TRASH MONITORING SYSTEM FULL

SMART TRASH MONITORING SYSTEM FULL

So the most obvious way to make it smart would be to detect if it is getting full and then send a notification to the personnel responsible for clearing it. IntroductionĪ trash can is one of those ubiquitous things, which hardly gets any attention until it is full and the trash seems to spill out of it. If you don’t have an account yet, please sign up here. Note: This project requires a functional account with IoTIFY. This use case is one of the many ones, around IoT, which empowers the things to talk to us, instead of we checking on them. Towards the goal of building a smarter planet, we present to you a prototype of an IoT-enabled trash can. To get started with Smart Trash Can powered by IBM Bluemix, please follow our step by step guide. Knowing that the ultrasonic velocity is of X m/s, the Distance can be calculated as: This is because the formula is used to measure the total distance traveled by the ultrasonic waves, hence it accounts for both directions of travel. Note that there is a 2 x factor in the equation. Knowing that, the distance can be calculated by:Ģ x Distance = (Echo Duration) * (Ultrasonic Velocity) In our application, trigger is connected to the pin 5 (GPIO) and echo is connected to pin 6 (GPIO). The length of the signal is proportional to the distance measured, and is hence used to measure the actual distance. The trigger can be considered a simple pulse that turns the sensor on, each time a distance is going to be measured. One GPIO connection for the trigger and another GPIO connection for the echo. This sensor requires two connections to the Raspberry Pi GPIO. The user guide documentation of this sensor, including functioning information, can be found here. To measure the trash fill level we will use the most popular HCSR04 Ultrasonic distance sensor. the top of trash can.Īs an embedded system, we will use an emulated Raspberry Pi platform (based upon Raspberry Pi® 2 Model B+). It also simplifies the design because all the circuitry could be contained at one place, i.e. Therefore measuring empty space remains most practical way to measure the fill contents. However due to the fact that trash contents could vary in nature (such as solid waste vs plastic or paper) measuring weight could not guarantee an accurate fill level. Another possible measurement could be measuring the weight of the trash can via a load cell (weight sensor). The measurement of Trash can fill level could be done by multiple means such as measuring the distance between the lid and trash content level. The project consists of an emulated Raspberry Pi connected to digital input/output and a ultrasonic sensor. Interfacing with IBM bluemix, one of the leading IoT cloud platform.Interaction with hardware such as reading digital input and output.Basics of measuring empty distance through reflection of ultrsonic wave.Wouldn’t it be nice if the vehicles know in advance which trash can should be picked and which could be skipped? You could build one right away. Last, but not least, the traffic congestion due to slow moving vehicles like trash pickup truck is really annoying. Did you ever find yourself wanting to adjust garbage into an overflowing trash can because the neighbor had a big party last night? Or you could not bear the nauseating smell of the trash decomposing in front of your house because the summer is unusually hot and the waste collection only happens once in 3 days? The smart trash can project is your solution! An overflowing trash can be not only aesthetically unpleasant, it could also be a health hazard for communities, especially in warm environments. Since the generation of trash is dynamic in nature, it often results in some trash cans getting overloaded and leaking while other remain almost empty. Current mechanisms do not take into account the actual fill level from containers, and instead schedule collection on predefined intervals. Waste management is one of the vital function of a smart city. Simulate a connected trash can in cloud to build a complete prototype for a citywide Smart Trash management application.

Sensor Ultrassom HC-SR04

É um sensor que mede distâncias que funciona da seguinte maneira: ao emitir um sinal ultrassônico de alta frequência, ele se propaga no meio na velocidade do som e que, ao atingir um objeto, o sinal retorna (eco) refletido para o módulo HC-SR04. Desta forma, a medição da distância entre o sensor e o objeto é calculado com base no tempo entre envio e retorno do sinal ultrassônico. Você pode usar o Módulo Sensor HC-SR04 com Arduino.

Ultrasonic Distance Sensor (HC-SR04)

https://thepihut.com/products/ultrasonic-distance-sensor-hcsr04?variant=1054704288¤cy=GBP&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gclid=Cj0KCQiAmL-ABhDFARIsAKywVaeMl2Zck8HRdz4mdvPy14UsCY0VII4O2NmzVnShRgXbGvYhrO7RRckaAlsAEALw_wcB

The HC-SR04 Ultrasonic Range Sensor uses non-contact ultrasound sonar to measure the distance to an object - they're great for any obstacle avoiding systems on Raspberry Pi robots or rovers!

The HC-SR04 consists of two ultrasonic transmitters (basically speakers), a receiver, and a control circuit. The transmitters emit a high-frequency ultrasonic sound, which bounces off any nearby solid objects, and the receiver listens for any return echo.

That echo is then processed by the control circuit to calculate the time difference between the signal being transmitted and received. This time can subsequently be used, along with some clever math, to calculate the distance between the sensor and the reflecting object!

The HC-SR04 Ultrasonic Range Sensor Features:

Arduino Uno y Sensor de ultrasonido

En esta clase trabajamos con un sensor de ultrasonido, el cual, siendo conectado correctamente, devuelve valores de posición de los objetos que están frente a el. Utilizando un Arduino, un protoboard, varios cables y dicho sensor de ultrasonido pudimos lograr lo esperado. A continuación presentaré el código programado en Arduino.

#include <HCSR04.h>

int triggerPin = 2; int echoPin = 3; UltraSonicDistanceSensor distanceSensor(triggerPin, echoPin);

void setup() {  Serial.begin(9600); }

void loop() {  double distance = distanceSensor.measureDistanceCm();  Serial.println(distance);  delay(200); }
