DHT11 digital temperature and humid

DHT11 digital temperature and humidity sensor is a temperature and humidity composite sensor with calibrated digital signal output. It uses special digital module acquisition technology and temperature and humidity sensing technology. The sensor consists of a resistive humidity sensing element and a NTC temperature measuring element, which has the advantages of superior quality, ultra fast response, strong anti-interference ability and high cost performance. Each DHT11 sensor has been calibrated in a very accurate temperature and humidity calibration laboratory. The calibration coefficients are stored in OTP memory in the form of program. These calibration coefficients are called during the processing of the detection signal inside the sensor.
