As the development of wireless communication technology, the WSN (wireless sensor network) has been used from the field of military to ISM (Industry, science and medicine), which plays an important role in these areas. The technology of information collection done in wireless sensor network has been developped from simplify to integration and network. ZigBee is a wireless tenology with low speed, which is mostly used in WLAN (wireless local area network). ZigBee is usually used in the condition with small datas, low data rate, small scope, high security and low power operation.This rsearch selected ZigBee technology as the software basic of the WSN, designed the WSN network platform based on ZigBee technology, developed the network communication protocol.
