Abstract：This article proposed a hardware/software designing method with intelligent measuring and controlling system in greenhouse based on Verilog HDL and FPGA．This system is designed by using FPGA chip EP2C8Q208C8 produced by Altera Company combining with ADC0809 module to finish the data acquisition．Meanwhile，the acquired information will be displayed on LCD．The upper computer interface will be realized by programming with VC++．The upper computer interface can not only display the real-time environment information，but also show the changing curve of the acquired data．For controlling greenhouse，we apply sectional control method，and implement wireless control by using wireless module of serial relay．Based on hardware circuit，this designing method has a high clock frequency，can response timely，and is able to complete the acquisition and display of temperature and humidity in greenhouse，and thus to controll the greenhouse．
