In day to day life human experimentation is tiresome and also gives improper outcomes for estimating the environmental change. In this paper we discuss how to replace manual maintenance of aquariums with an automated system using IoT to automatically monitor, control, and provide real-time status of pressure, temperature, water level, and the light intensity to applications running on user smartphones. It also contains water level management, which will monitor the conditions such as overflow and underflow of water level. The aquarium will perform the lighting automatically.
