System Realization
As shown in Fig.1, this system consists of sensor nodes for temperature, humidity, leaf temperature, leaf humidity, database server for collected data storage, and relay nodes which controlequipmentssuchaswindow,heater,ventilator,etc.automaticallythroughtheenviron- ment information collected in real-time. The base node can receive the data from the sensor nodes and store them into database. Then, the base node can send them to the remote control system via internet. The remote control system can make analyze the corrected data and then make decision. Finally, the control signals will be given the greenhouse to maintain optimal environment via internet. These sensor nodes and base node can be deployed at any spot in
