【Abstract】 The research of the wireless sensor network is a hot area. It has the widespread prospect in environment monitoring, military, medical industry, family intelligence monitoring and other commercial domains. The wireless sensor network has many characters, such as thick density of the sensor nodes, the frequent changing of the network analysis, the power, computation ability and the data limited storage ability of the nodes and so on. But the energy consumes is the main problem to embarrass its spreading.With the wireless communication developing constantly, facing to the low cost equipment, Zigbee technology appeared in recent years. It is a bidirectional wireless communication technology which is less distance, lower complex, lower power loss, lower data rate and lower cost. It mainly used in the areas of automatic controls, the long-distance control domain and the home use equipment network. The Zigbee technology and the wireless sensor network technology can be united to provide the better solution for the healthy guardianship, the safety system, the building automation and so on.With this researching background, this paper introduced the design of a wireless sensor network system based on the ZigBee technology. United with the subject of remote health guardianship, it elaborated the result of the designing of the wireless nodes.Firstly, the paper introduced the present situation of the wireless sensor network, the concept of ZigBee and the research background of remote healthy guardianship. The data gathering using by the wireless network is attracted by the world with the sensor technology getting more and more mature. The wireless sensor network is made by lots of sensors nodes which is organized automatically based the wireless communication technology. Although the blue tooth, Ad hoc and other methods are the hot topics in the area, Zigbee (IEEE802.15.4) is the most competitive WSN network protocol at present. It is mainly established by the IEEE 802.15.4 groups and the ZigBee Alliance organization including the hardware and更多还原
