Design of Water Quality Monitoring System for Aquaculture Based on ZigBee

Abstract

The aquaculture industry is developing on a large-scale. Now most aquaculture households use the artificial way of water quality diagnosis, decision-making and adjustment, the data cannot accurately reflect the water quality status. The data acquisition node used distributed self-organizing network structure, it accomplished the detection of water temperature, pH value, dissolved oxygen, conductivity and other water quality parameters. ZigBee wireless communication module was used to the data exchange between the data acquisition node and router node, router node and coordinator node medium. The synchronization of the whole network node to sleep and wake up was realized using the time synchronization algorithm, it greatly reduced the system power consumption. The system was tested in Sanya university natural lake, it can realize the monitoring function of aquaculture water quality parameters, all-weather real-time transmission of information and automatic regulating or remote manual adjustment according to the preset dissolved oxygen content.
