Development of an Automatic Water Exchange System for Smart Freshwater Aquarium

This paper presents an automatic water exchange system designed for a freshwater aquarium. The automatic water exchange system (AWES) was developed to improve the aquarist’s work. Replacement of water in an aquarium is one of the basic maintenance activities and should be performed regularly. In case the process of pouring in and out of the water itself requires a lot of time and strength from the aquarist, the automation of this operation is proposed. The automatic water exchange system consists of a water discharge system, a water filling system, and a security system. Additionally, to simplify user operation, a dedicated mobile application for the Android system has been created. The developed AWES system allows for regular changing of water in aquariums as well as enables effective and simple control of water flow and temperature.
