Abstract: Greenhouses can effectively reduce the impact of natural disasters in agricultural producing, so monitoring of meteorological elements greenhouses became a pressing need. Greenhouse is no longer isolated individual in this design, but rather combines them into a network. A greenhouse is a node, a node can be a region. The author designed the network of environmental parameters capture terminal and monitoring center of two parts, collection terminal with ADAM-4000 series as the control center, responsible for collecting greenhouse environment information, through the serial port to transmit the monitored data to the monitoring center on the show and back to the database for historical data in SQL Server queries.
