Arduino - Humidity Sensor - Arduino Project Hub

Humidity Sensor (DHT22) The DHT-22 (also named as AM2302) is a digital-output, relative humidity, and temperature sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and sends a digital signal on the data pin. In this example, you will learn how to use this sensor with Arduino UNO.
