针对目前水质监测的需求,提出一种基于无线传感器网络的水质环境监测pH值感知节点硬件实现方案.该设计方案主要包括pH值水质参数采集模块、微处理器模块、无线收发模块和电源模块4部分,可对不同湖、河流等水环境参数pH值进行实时监测.本文详细介绍pH值感知节点的每个功能模块以及程序流程.由于采用了无线传输方式,该系统解决了有线通信方式存在的部署困难,难以扩展、升级等诸多问题,具有低功耗、低成本、部署灵活、维护方便等优势,具有广阔的应用前景.%In order to meet the requirement of water quality monitoring, the hardware implementation scheme of pH value sensor node based on wireless sensor network is proposed. The design scheme includes four parts: pH value acquisition module, microprocessor module, wireless transceiver module and power module, which can be used to monitor pH value of the lake, river and other different water environment. The hardware modules and software flow are introduced in detail. As a result of wireless transmission, the system solves the difficulties of development, expansion, upgrade of wired communication, which is of low power consumption, low cost, flexible deployment, easy maintenance and other advantages and it is of a broad application prospects.
