Wireless Sensor Network for Continuous Monitoring Water Quality in Aquaculture Farm

The Digital Wireless Monitoring System for water quality continuous measurement in aquaculture was developed based on IEEE802.15.4 standard and ZigBee. Multi-parameter water quality node, temperature chain node, routing node and an on-site monitoring center were designed and implemented. Multi-parameter water quality node was created for measurement of DO, EC, Water Lever and temperature in sea cucumber ponds. A temperature chain node is designed to monitor temperature profile change especially. Three types of energy supply were adopted to achieve demand of indoor and outdoor application in aquaculture farm. Both multi-parameter water quality node and temperature chain node are reduced funcition devices, which send measurement data to routing node. The Routing node used to extend the range of continuous monitoring in aquaculture farm. The DWMS with six multi-parameter water quality nodes, two temperature chain nodes, three routing nodes and one on-site monitoring center was integrated and evaluated in Marine Aquaculture Demonstration Center, Dongying, Shangdong, P. R. China. Continuous monitoring data revealed that the system based on WSN was cost effective, easy-to-use, and reliable.
