Development and Implementation of a ZigBee-Based Regional Water Quality Monitoring System: Design, Technologies, and Application

Abstract

Water pollution not only significantly impacts people's daily lives but also causes considerable harm to the flora and fauna in surrounding water bodies. Traditional methods of water quality testing involve manually collecting samples from the source and transporting them to a local laboratory for analysis, a process that is time-consuming.Therefore, there is a growing need for a novel water quality monitoring system that provides timely feedback. With advancements in wireless sensor network technology, wireless methods are increasingly being utilized to establish water quality monitoring systems. This paper proposes a wireless water quality monitoring system based on ZigBee technology, juxtaposed with traditional water quality monitoring methods.The system employs Texas Instruments' CC2530 chip as the central component, with sensors selected for relevant water quality parameters forming the hardware detection module. ZigBee functionality for each module is implemented through the Z-Stack protocol stack. Remote data processing is managed via PC software developed using LabVIEW, which processes data such as temperature, turbidity, and chemical oxygen demand (COD) received from the ZigBee network.This system facilitates real-time monitoring of water quality parameters. The ZigBee end-nodes collect data on water quality parameters through relevant sensor modules. This data is then transmitted to the ZigBee coordinator via the ZigBee network, which subsequently aggregates the data and sends it to a remote data processing center for comprehensive analysis.
