Abstract: This paper designed a greenhouse intelligent control system of two levels monitoring model mainly based on STM32.One was basement control including environmental information collection and automatic control， and the other was remote control. Base monitoring supports environmental information realtime display， history query and change curve display， which can set the ideal growing environmental parameters by the friendly manmachine interface using the touch screen design. The system can make automatic control of greenhouse environment to serve the needs of crop growth， which was based on the set of environmental parameters and realtime acquisition of environmental information to control environmental control equipment. Remote monitoring control system adopted RS232 communication protocol with the base connection, and it had the function of parameters setting， realtime data display and historical query. The system also supported manual mode control in response to the sudden alarm control. Test analysis showed that the system of greenhouse environment monitoring has good practicability and reliability.

Key words: STM32, intelligent greenhouse, remote control
