Development of Automated Real-Time Water Quality Monitoring and Controlling System in Aquarium

The aquaculture industry significantly impacts food and the world economy, especially in countries that depend on marine and river resources. Fish farming in large tanks is getting more attention as this can be done anywhere without searching for sea, river and pond areas. However, the water quality in the rearing tank must be monitored and controlled continuously, which causes problems because maintaining the water quality requires expertise and is time-consuming. This paper proposes an automated water quality control system consisting of various sensors, microcontrollers, servers and mobile applications that continuously monitor and control water quality. Water quality parameters are measured using sensors, and data is sent to the microcontroller. The microcontroller processes the received data simultaneously, sends it to the server, and activates the actuator based on the situation. Data on the server can be monitored and controlled by a mobile application. The system achieves an excellent real-time performance and high practicability in the future to encourage technological advancement in the aquaculture industry.
