According to the present situation of temperature and humidity control, a control system on temperature and humidity of greenhouse is designed, consisting of hardware circuit and software design. The system can accomplish real-- time control on temperature and humidity, taking MCU AT89C52 as control core and SHT71 as sensing element of temperature and humidity. MCU and intelligent sensors are linked together, collecting and processing measured datas with intelligent sensor. Real - time temperature and humidity values can be displayed through LCD12864. When temperature exceeds the al- lowable range, the motor will be started to adjust the temperature, so as to management and control the whole temperature and humidity system. This kind of temperature and humidity control system is easily managed with high precision.
