摘要
阐述了一种温度湿度智能数据采集的无线传感器网络,介绍了传感器节点的软件与硬件设计。该系统基于Z ig Bee无线通信协议设计,克服了有线传感器网络的局限性,避免了其他无线通信技术的高功耗的缺点,节点成本低、网络容量大、生存周期长。实验结果表明:温度测量精度为1℃,湿度精度为3%RH,可以广泛用于环境检测。
The wireless temperature and humidity smart data-collecting sensor network is discussed. The hardware and the software of sensor node are introduced. The sensor system based on Zig Bee protocol surmounts defect of wired sensor network and avoid the high-energy cost of other wireless technology. The node is low-cost, network capability is large, also the lifetime circle is long. Experimental result implies that the accuracy of this system is 1 ℃ in temperature and 3 % RH in humidity. It can be widely used in environment detection.
