Irregular manual feeding may negatively affect animal health. This study develops an automatic feeding system based on ESP32 with adaptive scheduling and precise portion control using real-time weight monitoring. The system integrates RTC DS3231, HX711 load cell, and a servo motor as the actuator. Weight data serve as feedback to ensure target portion accuracy. Testing indicates that the system reliably dispenses feed on time and in the correct amount. This system provides an effective and reliable solution for automated and precise animal feeding.
