[modifier] Principle analysis
Me Temperature and Humidity Sensor is composed of sensor DHT11, which comprises a resistive humidity-sensing component and an NTC temperature-measuring component. Calibration coefficients are stored in OTP memory in the form of program, and invoked by the sensor during processing the detection signal. Adopting single bus serial port, the sensor can implement two-way communication with the microprocessor by a bus only, and the time period of one communication is about 4ms. The system integration becomes quick and easy.
