Abstract: Taking greenhouse for research subject，environmental information such as air temperature，air humidity，soil moisture，soil temperature，CO2 concentration，light intensity and video images could be real-time acquired by internet of things technology.Then，the information was transferred to the intelligent management system of the host computer with the WSN and GPRS network in order to realize the remote automatic control of equipments such as wet curtain，water irrigation，internal and external shading，roof window，light supplement and so on.The system could provide the most suitable environment for crop growth in greenhouse，enhance intensive and intelligent management，reduce labor intensity and production costs，decrease occurrence of disease，and enhance quality of agricultural products and economic benefits.
