An egg sorting machine using a weight sensor was developed using low-cost, locally available materials and local manufacturing technologies to sort eggs into different sizes based on weight. The fabricated machine comprises several parts, including the transmission, transporting, and sorting mechanisms. The transporting mechanism is powered by a 15 RPM, 12V gear motor, chain, and sprocket for the transmission unit. The weighing and sorting unit used the Servo motor, Arduino Uno Microcontroller, and Load Cell with HX711 amplifier. Performance test results for the 360 table egg samples show that the egg sorting machine has an average sorting accuracy of 93.88% with a capacity of 889 table eggs per hour (4.05 seconds per egg). It shows that the machine is accurate. Thus, the machine reduces the use of manpower and drudgery of manual sorting while maintaining a higher accuracy and speed in sorting table eggs. It can be used in egg-laying farms to classify small, medium, large, and extra-large sizes. The annual income is Php 36, 421 and in 1 008 hours a year of sorting eggs, the machine was expected to meet its break-even period of 92,396.8 eggs per year, and it will reach its payback period after 0.39 years.
