Abstract: A remote wireless realtime monitoring system in the vegetable greenhouse is designed． The system is composed of monitors’ terminal, gateway’s node and monitor’s center． The data acquisition of environmental parameters is implemented by wireless sensor network with ZigBee communication protocol in monitors’ terminal nodes． The wireless sensor network is composed of ZigBee module whose core is CC2533 module. The data aggregation function is implemented in server sides who is developed with the microprocessor PXA270 of ARM10 and Linux operation system. The ZigBee network is used to aggregate data from monitors’ terminal nodes and the 3G wireless communication network is adopted to realize the remote data transmission function．The adoption of ZigBee technology and 3G technology satisfied the requirements of wireless data acquisition and data transmission for environmental parameters of vegetable greenhouse．At the same time， the problems are effectively solved including wiring problems, nodes’ immobility and system maintenance difficulties. The proposed system is suitable for environmental parameters’ monitoring of the vegetable greenhouse．
