DHT22 temperature and humidity sensor (AM2302)

The AM2302 humidity sensor is presented in a plastic body ideal for mounting on a panel or the like. It uses a capacitive sensor that returns a digital signal with the measurement (analog pins are not required). It is very easy to use, although it only allows one reading every 2 seconds. The DHT22 temperature and relative humidity sensor delivers a calibrated digital signal, ensuring high quality and reliability over time, as it contains a 16-bit built-in converter.
