Automatic Aquarium Water Change System With Real Time Monitoring Through IoT

As Malaysia's pandemic is coming to an end, all the hobbyists will begin to return to their respective work life, which for some even includes traveling overseas. This will leave their aquatic pets unattended; their pets might starve to death or, even worse, get poisoned by the dirty tank water, which leads to the death of fishes as well. The main aim of this project is to create a self-sustainable aquarium system through real-time IoT control using Arduino and ESP32 as microcontrollers. The system implemented will be well equipped with a feeding system, water parameter monitoring, and a water change system. The methodology used will be a user-based input feeding system that can control the amount of food being dispensed to prevent any overfeeding. It is observed that the food being dispensed is more consistent compared to human feeding manually. Besides, there will be a water quality monitoring system where the temperature and the pH value are kept at optimal levels. Whenever the water parameters exit the optimal condition, respective actuators will be turned on to return the water quality back to optimal conditions. All the parameters will also be displayed on a web and mobile application platform whereby users can get real-time streaming and live situations from the application. Some future enhancements that can be performed on this project will be using more specific sensors and actuators to create a more precise and accurate system.
