Working…

The DHT22 is a popular sensor used to measure temperature and humidity. It’s also known as the AM2302 and is part of the DHT (Digital Humidity and Temperature) sensor family. The DHT22 operates using a digital signal protocol, making it easy to interface with microcontrollers and other digital devices.
