摘　　要：针对家居安防智能化的需要,将无线传感器网络的用于家居安防,设计了一种探测非法入侵的无线传感器网络节点;该节点以超低功耗的nRF9E5无线单片机为核心,通过热释电红外传感器对非法入侵进行探测;探测节点可将热释电红外传感器探测到的入侵信息通过无线方式传送至家庭网关,在发出声光报警之同时,还可通过系统将入侵信息传送给用户;测试结果表明,该设计方案成本低,性能可靠,实现了对8m范围内非法入侵者的探测。Abstract： Wireless sensor network （WSN） was used to realize the automatic monitor in family security system. An anti--intrusion node that is used to detect the illegal intruder on family was designed, which consists of the central microprocessor nRF9E5 and PIR sensor. The detection node reported the information to the central controller through wireless Communication, and then used the guard system to accom- plish intelligent repelling against intruder. The test result shows that the designed node has a good performance of detecting the intruder. The detecting distance is around 8 meters.
