Fish keeping is a popular trend. Fish keeping is itself an industry which comes in agriculture. Fish keeping is not an easy job; we always need an aquarium or a pond for that. The hobby of fish keeping is broadly divided into three- freshwater, brackish, and marine. Among all these three, freshwater is considered to be the most popular hobby of keeping fish because it is easy to handle freshwater fish and aquariums. It requires a lot of manual work to take care of the aquarium for instance timely change of water, regular feeding of the fishes, maintaining the turbidity level and the temperature of the water in the aquarium. Hence to reduce the manual work, the research is based on the project, IOT and ARDUINO based Fish Aquarium that has been designed to save labor time through making the system automated. It is a prototype functioned to feed the fishes on a regular time intervals, keeps the temperature and the turbidity level under control. The Wi-Fi Module attached to it sends the status of the aquarium like temperature level, turbidity level, feeding etc on your respective device like cell phones.
