Aquaculture Monitoring System using Arduino Mega for Automated Fish Pond System Application

Fish farming industry has become one of the sources of income to people who are involved in business. An entrepreneur in this industry can make more money when the fish pond is equipped with the suitable device. With the existence of such device which capable in controlling the water level, monitor the temperature and so forth; then the entrepreneur has nothing to worry since everything is automated and can be monitored closely by just using a smartphone with Blynk application. This system is designed to control the water level, monitor the water temperature, automatic feeding and automatic water replacement of an aquaculture environment. The user gets to view the live measurement of the water temperature and water level. This study is limited to only a small aquarium where the maximum height is 15cm since it is only a prototype. The Arduino Mega 2560 is used as the microcontroller in this study since its program is easy to change and the language of this microcontroller is more familiar rather than other microcontrollers. This study results in a reliable water level controller which works continuously to regulate the water level to the desired water level. Besides that, this system also capable to feed the fishes automatically every 90 minutes and change the water in the aquarium for every two days. The graph of water level and the water temperature is updated from time to time and the data can be downloaded if the user intended to do so.
