Desig Of Wireless Sensor Network Based On Zigbee

Wireless sensor network technology combines sensor technology, embedded computing technology, modern wireless communications network technology and distributed information processing technology has become a interdisciplinary front field of study. ZigBee technology based Wireless sensor devices can achive many advantages such as low-cost, low power, simple to implement etc, and becomes a focus in research and application of wireless sensor network.The main work of this paper is designing ZigBee wireless sensor hardware systems based on the CC2430, programming ZigBee-based sensor system software of data collection and communication, and finally completed a small ZigBee wireless sensor networks for temperature and humidity monitoring.This paper analyzes the ZigBee technology standards and network protocols, ZigBee-specific network architecture and protocol layers were studied. According to the system requirements for wireless sensor networks, a hardware design proposed, including the CC2430 and RF circuit design and sensor circuit design. Completed the printed circuit board production and debugging. Completed the application software design of wireless sensor node. The performance of sensor network system has been tested, and achieved project requests. The work of design and debug on hardware and software is a good reference for the future research of ZigBee applications.
