摘要
针对北京城市绿地节水灌溉的需要,以CC2530无线射频芯片为核心,设计了基于无线传感器网络(WSNs)的低功耗终端数据采集节点和协调器,给出了节点硬件的低功耗设计思路,构建了绿地墒情监测硬件平台。实验结果显示:系统能够准确获得环境温度、土壤水分的数据。节点睡眠时的工作电流仅为10μA,节点实际平均工作电流仅为0.265 mA,功耗性能优于市场同类产品约30%。
Aiming at water-saving irrigation needs of urban green space of Beijing,using CC2530 RF chip as core,design a low power consumption terminal data acquisition nodes and coordinator based on wireless sensor networks (WSNs),gives a low power consumption design ideas of node hardware,build a green moisture monitoring hardware platform.Experimental results show that the system can accurately obtain datas of ambient temperature and soil moisture.Node operating current is only 10 μA during sleep,node actual average operating current is only 0.265 mA,power consumption performance is prior to similar products in market about 30 %.
