Since the greenhouse has characters of temperaturehumidity uneven distribution, strong coupling and traditional control strategy can't achieve the ideal control effect, the greenhouse monitoring system based on internet of things (IOT) is designed. The system uses a fuzzy neural network which has good control effectiveness in complex and changeable greenhouse system. Perception layer using ZigBee protocol for wireless communications, and greenhouse environment can be controlled by site control

... oftware/master node, which makes the system more effective and stronger. The master node uses mobile communication network to send sensing layer data to application layer and can send alarm SMS. This system has the characteristics of low cost, simple structure, flexible networking and easy extending, which adapts to the requirements of complex greenhouse control.
