Description

The DHT22 temperature and humidity sensor is a low-cost high precision humidity and temperature sensor with a single wire digital interface, meaning many of these sensors can be strung (daisy chained) together from one digital pin. The sensor is pre-calibrated and doesn’t require extra components so you can get right to measuring relative humidity and temperature.
