摘要
为解决目前鸡舍二氧化碳监测系统存在的布线复杂、节点功耗大等问题,设计了一种基于无线传感器网络的鸡舍二氧化碳实时监测系统。该系统以Atmega16L为核心,NRF905射频芯片及其外围电路作为无线通信模块,二氧化碳红外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,对鸡舍内不同点的二氧化碳进行实时监测,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,系统能够实现鸡舍二氧化碳的远程、准确测量。
A henhouse carbon dioxide real-time monitoring system was designed based on wireless sensor network to solve problems wiring complex, node power, managemen which exist in the henhouse carbon dioxide real-time monitoring system. Atmegal6L chip was used as the core, NRF905 chip and its peripheral circuit as wireless communication module, SHTll carbon dioxide sensor and its peripheral circuit as sensor module, to write communication protocols and applications. Henhouse different points carbon dioxide 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 , the results showed that this system can realize the henhouse carbon dioxide remote, accurate measurement.
