Abstract: Since the greenhouse has wide range and many environmental factors， we developed the greenhouse control system based on CAN bus and GPRS. The system can collect temperature， humidity， light and CO2 concentration and other environmental parameters. All data is uploaded via CAN bus and GPRS to a remote host computer. The greenhouses temperature and humidity， ventilation equipment， supplementary light switch can be controled by the remote host computer. The remote software is developed by KingView. The experiment showed that the system works well and it can satisfy the needs of automatic monitoring of greenhouse.

Key words: greenhouse, monitor, CAN bus, GPRS, KingView
