A Design and Implementation of Aquaculture Environment Parameter Monitoring System Based on Wireless Sensor Networks

Abstract

In this paper, a real-time and remote monitoring system based on wireless sensor network for aquaculture environment parameters was designed and implemented to overcome the defects of traditional means, such as small monitoring scope, wiring problems and construction difficulty. The system used sensor nodes to obtain data of water temperature, pH value and dissolved oxygen concentration, sink node to collect monitoring data that was sent to the remote monitoring center by a GPRS network. And then the data was analyzed, processed, stored, and showed by figures and tables in the central monitoring computer. Experiments in the laboratory field were conducted in five different node deployments to verify the accuracy and reliability of the system. The maximum relative error of temperature was 2.7%, and pH value and dissolved oxygen concentration were 6.7% and 7.6%, respectively. Results indicate that the system can collect the temperature, pH value and dissolved oxygen concentration, and transmit data remotely to the remote monitoring center, providing with the characteristics of working stability and reliability.
