Urbanization has dramatically increased during the last few decades. An increase in garbage output is occurring at the same time. Because of the incompetence of the authorities and the irresponsibility of the people, foul odors from rotten wastes may continue untreated for a lengthy period of time and cause long-term issues. This could possibly result in terrible diseases. With the help of an Arduino Uno board, which interfaces with the servomotor, infrared sensor, and ultrasonic sensor in this project, a smart litter box is constructed on a microcontroller-based platform. An infrared sensor and an ultrasonic sensor are positioned at the top and bottom of the trash can, respectively, to measure its level and where the bin should be stopped. The threshold height has been set at a specific height. The servo motor will activate and open the lid of the litter basket when someone approaches it, allowing them to dispose of their trash in the bin. This is how Arduino will be programmed. Once these intelligent baskets are widely adopted, they can replace our present conventional trash cans and effectively manage waste by removing the need for unneeded rubbish piles to be dumped on the side of the road.
