DESIGN AND DEVELOPMENT OF A SMART FEEDER BASED ON MICROCONTROLLER WITH FEATURES FOR AUTOMATIC FEEDING TIME AND PORTION CONTROL

Abstract

Catfish farming requires a regular and efficient feeding system to support fish growth and health. Common issues that often occur in the field include delayed feeding, improper feed quantities, and difficulties in monitoring leftover feed. This study aims to design and develop a microcontroller-based Smart Feeder using the ESP32, which can automatically control feeding time and portion sizes. The system development method uses the ADDIE approach, consisting of five stages: Analyze, Design, Development, Implementation, and Evaluation. The development of this tool involves key components, including the DS3231 RTC for time control, load cell + HX711 for feed weight measurement, servo and pump motors for the feeding mechanism, ultrasonic sensors to monitor leftover feed, and an I2C LCD to display information. Testing was conducted to evaluate the tool’s functionality, including testing automatic feeding time, feed portion measurement, and monitoring leftover feed. Test results show that the tool functions as expected, being able to feed at the predetermined time, accurately measure feed portions, and monitor leftover feed in the container. Additionally, remote control via mobile applications adds comfort for users. User evaluations indicate positive results, although there are suggestions for further development, such as improving tool durability, adding a notification system, and advanced monitoring features. Recommendations from this research include adding automatic notification features
so users can receive updates on feed status, as well as improving material quality and tool durability for long-term use..
