Design and development of a LoRa based Water Quality Monitoring System

Abstract

The traditional aquaculture industry expends huge manpower to monitor and maintain water quality of fish pond to ensure the survival rate of cultured species. The automated water quality monitoring system can effectively reduce the burden on water quality monitoring for farmers. However, some automated water quality monitoring systems deployed in broad fish farms have the problems of limited communication distance between devices and lack of monitoring capabilities for low power and remote water quality monitoring. Therefore, this paper integrates many water quality sensors, long-range (LoRa) wireless communication technology, and open source cloud services to develop a LoRa based Water Quality Monitoring System (LWMS). The LWMS was actually deployed on the fish pond for experiments, the results show that the proposed device provides the ability to monitor the fish pond water quality over long distances.
