You can use the DHT22 (or AM2302) humidity/temperature sensor and the Arduino UNO board to read data ... In the sketch you can see that I use the Adafruit DHT library that is very simple to use and if ...

#include "DHT.h" #define DHTPIN 2 // Digital pin connected to the DHT sensor #define DHTTYPE DHT11 // DHT 11 //General Syntax: DHT dht(pin, sensor_number); DHT dht ...

Examples include both a "standalone" DHT example, and one that works along with the Adafruit Unified Sensor Library. Unified sensor library is required even if using ...

Using the wiring diagram helpfully provided by Adafruit I connected the DHT22 to the Arduino, with data flowing in on pin #7. Next I installed this DHT library for Arduino and then used this slightly ...

Arduino DHT11 Code for Interfacing the Sensor Module Now let’s look at the code for interfacing the DHT11 sensor. For that first install the Adafruit’s DHT sensor library and Adafruit Unified Sensor ...

Using the Internet of Things (IoT) in homes and industries it is possible to control any electrical or electronic equipment. Moreover, you can get the information from any sensor and analyse it ...
