The traditional temperature control is within the greenhouses suspension thermometer, temperature of workers on the basis of reading to adjust temperature in the greenhouse. If only by manual control human consumption already, also prone to error. Now, with the improvement of agricultural production scale, the number of greenhouse, the traditional temperature control measures is showing a lot of limitations. Therefore, in modern greenhouse system management usually automatic control system for temperature, humidity, light intensity, to control the growth environment of crops. This paper greenhouses with temperature, humidity, light intensity as the control of the environmental parameters, designed a kind of based on single chip microcomputer, the integrated use of the computer control technology, electronic technology, automation technology parameters automatic measurement and control system. The system uses AT89S51 as the controller, SHT11 as the temperature and humidity data acquisition system photosensitive resistance as a light intensity data acquisition system, can implement canopy temperature
