Aqua forms are increasing year on year with increase in the demand of fish foods. Maintaining fish farms is of greater challenge since the growth of fish is related with quality of water. Monitoring the quality of water in each tank becomes difficult and includes interference that is much more human. In this proposed research work, an intelligent automatic aqua monitoring system is introduced where the sensors and the inlet monitor the quality of water and outlet of fresh water is controlled through Arduino micro controller. Since the components used are cheap and Arduino is very simple to program the proposed method finds efficient and promising results in maintaining aqua farms.
