Smart live monitoring of aquarium—An IoT application

Abstract

Fondness for fish aquarium is a trendy affair. Thus, many of them welcome it in their home just as a hobby or an eye-pleasing tool. It looks beautiful and brings a charm to the house, but it’s not easy to maintain. It requires time-to-time care where its responsibility resides in freshwater, brackish, and marine. Between these three, freshwater holds a popular place of keeping fish because it is effortless to handle with freshwater fish and aquariums. Taking care of fish and aquariums is an intricate task like feeding fish on-time, maintaining temperature, and also managing the light, heater, and filter of the aquarium. Till now it has been a manual process, thus it demands a well turned-out technology. Thus in this paper, smart aquarium has been planned by keeping in mind, the problems of those who cannot take care of their aquarium on daily basis. The feeder is powered by servomotor which on trigger of a button feeds the fish, heater keeps the temperature of the aquarium under control, and we can also be in charge of the fluorescent lamp which helps in the growth of fish and plants. Proposed technology uses Raspberry pi Webcam server to capture live video stream of aquarium, feed fishes through servomotor using pulse-width modulation, relays are used to ON/OFF light, temperature control, filter control, and android app to allow the user to access various functionalities.
