The design uses embedded microprocessor EasyARM1138, E_play-89S52-core board and wireless data transmission module in order to mensurate the environmental parameters and transmit the data of the greenhouse vegetables. Design DS18B20 sensors, humidity resistance, MS4100 CO2 sensors, photo resistors to achieve canopy temperature, humidity, CO2 concentration, light intensity detection. Testing data is displayed in the next-bit machine by LCD display circuit and 52 single-chip，and through the control circuit to control the environmental parameters. Wireless data transceiver modules are used to achieve data transfer of 52 single-chip microcomputer and host EasyARM1138. The data processed by the microprocessor was sent to PC. PC has the functions of data display, storage and alarm by LabVIEW software.
