水质监测无线传感器网络的硬件设计

针对传统水质监测系统不能对水质参数进行实时在线监测，难以准确检测水质参数的动态变化、水质参数检测误差大等问题，提出了水质监测无线传感器网络（ WSNs）的硬件设计方案。系统主要通过核心单片机CC2530实现传感器节点设计，采用太阳能电池板进行供电，同时设计了采集温度、pH 值的硬件电路，并对硬件电路进行了稳定性试验。在 IRA 开发环境下，进行传感器节点和协调器的编程，使之能够进行通信。实验结果表明：系统温度、pH值的平均相对误差分别为3.06%，1.64%，提高了监测精度。

Hardware design of WSNs for water quality monitoring

Aiming at problem that traditional water quality monitoring systems can not real-time online monitoring water quality parameters ,it is difficult to accurately detect dynamic changes in water quality parameters,and water quality parameters detecting errors is large,propose a WSNs-based hardwave design scheme for water quality monitoring. This system mainly through core MCU CC2530 realize design of sensor node,and using solar panels for power supply,at the same time design hardware circuit to collect temperature,pH value,and stability test is carried out on hardware circuit. At the same time,in IRA development environment,programming of sensor node and coordinator is carried out to communicate. Experimental result shows that average relative error of temperature and pH value is 3. 06%,1. 64% respectively,and improve monitoring precision.
