    DHT11 digital temperature and humidity sensor is a digital signal output containingalready calibration the temperature and humidity of the composite sensor.It used the digital module for acquisition technology and temperature and humidity sensor technology to ensure that products with high reliability and excellent long-term stability.

    Sensors including a capacitive are wet components and a NTC (temperature sensor, and with a high performance eight single chip connected.Each DHT11 sensors in the extremely precisely humidity calibration chamber to the equipment.In the form of calibration coefficient program stored in memory of a OTP, sensor detection signal processing in internal process we call these calibration coefficient. Wired system serial interface,make the system integration become simple and quick.
