This project showcases the use of an Arduino and a DHT11 sensor for real-time IoT applications. It includes various example codes for testing the sensor, connecting to the Blynk IoT platform, and ...

That’s an Arduino wired up to a DHT22 temperature and humidity sensor ($9.95 from The Robot Shop). Using the wiring diagram helpfully provided by Adafruit I connected the DHT22 to the Arduino, with ...

Code Implementation: o The Arduino program is written using the DHT library, which simplifies communication with the DHT11 sensor. o The program initializes the sensor and continuously reads ...
