Zigbee technology is a short distance, low rate, low power consumption, low cost and high reliability of wireless munication technology, mainly suitable for automatic control and remote control, you can embed a variety of devices, very suitable for the task as anization of WSN, these characteristics make the technology for low power consumption, low cost and low rate wireless munication market vacancy, its application prospect is very optimistic. This is the theoretical analysis of Zigbee technology, analyzes the working mode of Zigbee technology, bining the domestic existing sensor technology, wireless sensor work system for greenhouse environment data acquisition scheme is proposed. Build a WSN through Zigbee wireless munication technology. The system consists of sensor nodes, routing node, central node and PC monitoring platform. The system uses a tree topology, the temperature of the sensor nodes join the work, the light intensity and rainfall data colle
