An IoT- Based Automatic Fish Feeder

Fish owners and small-scale aquaculture systems often face difficulties in maintaining regular feeding schedules due to busy routines or absence from home. Irregular feeding can affect fish health, growth, and water quality. This project presents an IoT-based Automatic Fish Feeder for smart and remote fish feeding, a web-based system that allows users to control feeding operations through a Wi-Fi connected interface. The system is developed using an ESP32-CAM microcon-troller integrated with a servo motor attached to a food container to dispense a controlled amount of fish feed. When a feeding command is given through the web interface, the servo motor rotates and releases a measured quantity of food into the tank. The ESP32-CAM module also provides a live camera view, enabling users to monitor the feeding process and confirm that feeding has occurred successfully. The system operates through wireless connectivity without requiring com-plex additional hardware, making it suitable for home aquariums and small-scale fish farming setups. By enabling timely feeding and remote monitoring, the system improves fish care while reducing manual effort. This approach supports Sustainable Development Goal 2 (Zero Hunger), Sustainable Development Goal 9 (Industry, Innovation and Infrastructure), and Sustainable De-velopment Goal 12 (Responsible Consumption and Production) by promoting efficient and re-sponsible feed management in aquaculture systems.
