GEMS: A WSN-based greenhouse environment monitoring system

To meet the special requirements on micro-climate raised by the greenhouse in Northeast China, we develop a WSN-based greenhouse environment monitoring system. We decrease the power consumption of nodes, reduce the complexity of system development and simplify the deployment of nodes by dormancy mechanism, single-hop transmission, and on-demand deployment. Gateway node transmits the sensor data to remote database by TD-SCDMA technology. Then, through Internet, people can get access to the environmental information of crops by network terminal. The advantages of this system include low power, low cost, simple structure and flexible extension. The experiments further proved the practicality and reliability of the system.
