Abstract
With computer network and communication technology progresses,new theoties,standards and technology will be endless.Wireless communication from the 3G wireless communication network to the wireless network access and to the IEEE802.11x wireless LAN,networks become ubiquitous,and our lives have become closer and closer, It enables people to lift the restraints of cables.In many wireless network technology,wireless network technology based on ZigBee with low power consumption,low cost,low complexity features loved by an increasing number of businesses and individuals of all ages.
ZigBee technology is particularly suited to small data throughput and network construction investment,the higher requirements of the network security,inconvenience frequent battery replacement or recharging occasions.Expected to be in consumer electronics equipment,intelligent household,industrial,medical equipment control,agricultural automation fields of applicaton.
In this paper,on the basis of the wireless sensor network protocol analysis technology,a method is proposed for measuring the temperature of wireless sensor networks,and the design and development of the corresponding wireless sensor nodes.The program is the use ofmicrochip CC2430 and DS18B20 and built on a ZigBee technologies wireless sensor networks.the network acts as a coordinating center for a number of nodes and terminal nodes togerher to form a star network. Coordination is respsible for the inquiries to the terminal node temperature information,terminal nodes will be responsible for the temperature sensors to collect informaation and feedback to the coordinator,so as to achieve a regional temperature monitoring purpose.
