Description
Compact module based on the DHT22 temperature and relative humidity sensor. It features a single-wire serial interface for easy use. The DHT22 sensor is calibrated with extreme precision; calibration coefficients are stored in OTP memory and recalled during the measurement process, so there is no need to recalibrate the sensor. It is particularly suitable for consumer products, weather stations, HVAC applications (Heating, Ventilation and Air Conditioning), etc.
