Description

Description:

This is DHT22 is a digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed).

Compared to the DHT11, this sensor is more accurate and works in a bigger range of temperature/humidity
