SMART DUSTBIN USING ARDUINO

This paper presents the design and implementation of a smart dustbin system utilizing Internet of Things (IoT) technology. The increasing demand for efficient waste management has led to the development of smart systems that improve hygiene and reduce human effort. This paper presents a smart dustbin design using the Arduino Uno R3 microcontroller, ultrasonic sensor, and servo motor to enable automatic lid operation. The system detects the presence of a user through distance measurement and opens the lid without physical contact, thereby promoting cleanliness and preventing the spread of germs. An optional load sensor is used to monitor the dustbin’s fill level, which can further be integrated with alert notifications. The prototype is cost-effective, easy to implement, and suitable for use in households, public places, and institutions. Experimental results demonstrate that the smart dustbin operates reliably and enhances overall waste disposal efficiency.
