Based on the DHT11 sensor, this module allows measuring temperatures between 0°C and +50°C and relative humidity from 20% to 90%. It has a single-wire serial interface that facilitates its use. The DHT11 sensor is calibrated extremely precisely, the calibration coefficients are stored in the OTP memory and are recalled during the detection 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. Dimensions (mm): 23x16x7, weight: 5 grams.
