Development of Water Quality Measuring System for Fish Cage Culture with Solar cell

Abstract

This study proposes the development of a solar-powered water quality monitoring system for cage culture with a measurement of water quality system using the Internet of Things technology (IOT) application. It is intended for measurement of water quality for the cage culture. In this study, there are three types of sensors that are important for the fish farming in cages were selected such as Dissolved Oxygen (DO) sensor, pH sensor and water temperature sensor. These sensors are connected to the microcontroller based on the IoTs platform. The detected signals are monitored on the application platform and the data notification is sent through the Line application platform and a siren alarm when the dissolved oxygen level drops below 3 mg/L. The system can monitor and the analyze the value of oxygen content the Dissolved Oxygen, amount of acid – base and the temperature in the water in real-time. The test results showed that the power obtained from the solar cell was about 67.57 watts and the instrument can properly control the DO concentration in a designed range. This system makes for the fish farmers in cages can prevent damage the water quality faults in the cage culture, thereby reducing the risk of fish.
