摘　　要：针对无线传感器网络实时监测和突发事件处理的应用需求,设计了无线传感器网络节点。节点采用超低功耗的MSP430F149单片机和具有多种工作模式的无线射频模块nRF905,采用了声音、磁性和加速度3种传感器,用于实现对环境数据的采集和目标信息的探测,同时通过蜂鸣器、麦克风以及音频信号的接收放大和解码电路实现节点间的测距。A kind of wireless sensor network node was designed,used for the surveillance and reconnaissance outdoors.It used the low-power micro-processor MSP430F149 and the wireless communication module nRF905.Three kinds of sensors were applied,including the sound sensor,magnetic sensor,and accelerometer sensor,which were used to gain the environment data and detect the targets.And the buzzer,microphone and the sound processing circuit were used to measure the distance between the nodes.
