An IoT-Based Smart Aquarium Monitoring System

Fish is one of the pets that need intensive care compared to others pet like cat, rabbit and hamster since they live in the water. Usually, fish had been abandoned with lack of care such as unclean water in the aquarium or fish breeding ponds. An IoT-based smart aquarium monitoring system is one of the solutions to cater the problems. This research presents a developed prototype of an IoT-based Smart Aquarium Monitoring System to keep a fresh water in the aquarium for fish life habitats. The system functions to monitor the fresh water for healthier fish life habitat. This system operates as fish feedings system and controlled by a smartphone in its operation. Arduino MEGA and NodeMCU controllers are used in the designed system. Wi-Fi communication on the NodeMCU is used between the smartphone and the controller to control the operation. Analog pH sensor is used to detect the pH value of water and display the value through the Liquid Crystal Display (LCD). The coding is created by using Arduino Software IDE while the BLYNK software used to create software applications for the Android operating system. The system is designed to monitor the pH value that is suitable with the type of fish life and control the fish feeding using smartphone in android application. This research is significant towards IR4.0 system development in supporting fish pets and larger project for fish breeding in the pond can be sampled with this project that contributes to economy impacts for the country.
