Abstract: Mechanization and automation level of intelligent greenhouse facility production in China is low, input-output efficiency is inefficient, operation economic benefits are poor, and technical requirements for measurement and control system of intelligent greenhouses are excessive, which is difficult for ordinary users to master, and limits use in greenhouses．An embedded greenhouse intelligent control system was developed by using microcontroller technology, reducing cost of greenhouse upgrading intelligence．It could meet intelligent control needs of new greenhouses, upgrade ordinary greenhouses to intelligent ones, reduce labor intensity, improve production quality, and promote modernization process of intelligent agriculture．
