Real-time temperature and humidity of the base station to monitor and control is particularly important. The design is based on microcomputer temperature and humidity measurement and control system, modular, hierarchical design. Using a new type of intelligent temperature sensor DHT21/AM2301 to achieve temperature, humidity detection，The temperature and humidity signals through the sensor signal acquisition and conversion into a digital signal, Then the signal is transmitted to the STC89C54RD+ data analysis and processing, display and temperature and humidity control circuit provides signals, realize the base station temperature and humidity measurement and control. Base temperature, humidity detection and ventilation system, air conditioning system, forming a base station room environment intelligent monitoring control system, intelligent on or off the ventilation or air conditioning, can achieve the purpose of power. The system has the advantages of simple circuit, high integration, stability, convenient adjustment, high detecting precision, which has practical value.
