DESCRIPTION

Temperature-Humidity Sensor, DHT22 Onboard
 

Overview

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

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