摘要
针对无线传感器网络节点体积小、能耗低、存储和通信能力有限等特点,从ZigBee协议栈的结构特点出发,提出一种基于ZigBee的无线传感器网络节点的设计方案。详细地阐述了构成传感器节点的各个模块的设计,即采用了CC2430芯片作为核心元件,使用温湿度传感器SHT11进行温湿度数据采集,并给出了节点软件设计方案。经过测试证明,该节点运行稳定可靠并具有较高的通信效率。
Considering characteristics of wireless sensor network nodes,which are small,low- power consumption, limited capacity of storage and communications, a design of wireless sensor network node based on ZigBee according to the ZigBee protocol stack characteristics of the structure is proposed. The detailed description of various modules of the node is given. It centers on CC2430 chip, with the SHT11 together to realize the acquisition of the temperature and humidity data. And connection of the software design is realized. It is proved that the operation of the node is stable, reliable and high efficiency of communications after the test.
