Managing waste and keeping public areas clean are big problems in many developingregionswherepeoplestilluseregulartrash bins.Handlingthelidofatrashbin by hand can spread germs, cause bad smells, and make places less clean. This study introduces a low-cost, easy-to-make smart trash bin system that uses an Arduino microcontroller. The system uses an ultrasonic sensor to sense when someone's hand or object is near the bin and automaticallyopens the lid with a motor. It also has an infrared sensor that checks how full the bin is and stopsthe system fromworking when it's full.The system is built with affordable and easy-to-find parts like an ESP 32, HC-SR04 ultrasonic sensor,L298N motordriver, DCgear motor,and a buzzer.The goalisto create atouch-free, cleanwayto disposeofwastethat worksin homes, offices, and publicareas. The prototype works well, detecting objects, controlling the lid automatically, and runs efficiently. This project shows how simple technology can improve sanitation and help create better waste management systems in the future.
