This is a calibrated digital temperature and humidity module with an onboard DHT22 (AM2302) sensor, which features higher accuracy and a wider measuring range than a DHT11.

This sensor can be used for detecting ambient temperature and humidity through the standard single-wire interface.

Comes with an XH2.54 3-pin cable.
