Design and Implementation of Smart Dustbin for Automated Wet and Dry Waste Segregation

The increasing rate of urbanization has significantly contributed to the generation of mixed waste, posing serious environmental and health challenges. Manual segregation is inefficient, labor-intensive, and often hazardous. This paper presents the design and development of a smart dustbin system that automatically classifies waste into wet and dry categories using embedded sensors and microcontroller technology. The proposed system utilizes an Arduino UNO, ultrasonic sensor, soil moisture sensor, servo motor, and relay module to detect waste type and direct it to the appropriate compartment. The implementation aims to assist in effective waste management and promote a cleaner environment through automation.
