摘要
本文设计了一种基于无线传感器网络的鸡舍温湿度实时监测系统,解决目前鸡舍温湿度监测系统存在的布线复杂、节点功耗大等问题。系统以Atmega16L为核心,nRF905射频芯片及其外围电路作为无线通信模块,SHT11温湿度传感器及其外围电路作为传感器模块,编写了通信协议和应用程序。该系统能同时对鸡舍内不同点的温度、湿度进行实时监测,并将数据发送给远程监控中心。试验结果表明:通过控制数据采样间隔和采取休眠等措施能降低功耗,系统测量的温度平均误差为0.203%,能够实现鸡舍温湿度的远程、准确测量。
A henhouse temperature and humidity real-time monitoring system was designed based on wireless sensor network to solve problems wiring complex, node power, consuming, existed in the henhouse temperature and humidity monitoring system . AtmegalSL chip was used as the core, NRF905 chip and its peripheral circuit as wireless communication module, SHT11 temperature and humidity sensor and its peripheral circuit as sensor module, to write communication protocols and applications. Henhouse different points temperature, humidity was monitored in real-tim, the data was sent to the remote monitoring center. The experiment showed that： power consumption can be reduced through controlling data sampling interval and dormancy, and the temperature error was 0. 203 % ,The results showed that this system can realize remote and accurate measurement of the henhouse temperature and humidity.
