Arduino and Ultrasonic Sensor Based Smart Dustbin for Efficient Waste Management

Abstract

Designing an effective and hygienic waste management system utilising an Arduino-based Smart Dustbin is the goal of this project. The trash can is divided into two sections: a permanent section that houses all the electrical parts and a detachable cover with a moveable flap. Two ultrasonic sensors, a servo motor, a breadboard, a buzzer, and an LED light are all parts of the system. When an item is detected by the first ultrasonic sensor, the servo motor is activated, lifting the flap for contactless trash removal. When the threshold is surpassed, the second sensor, which checks the garbage level, turns on the LED light to indicate that the bin is not yet ready for use. The motor is dormant and a buzzer alerts the user to empty the bin if they try to dispose of garbage during this period. By limiting the spread of bacteria and odours and ensuring that the trashcan is constantly accessible, the system provides an effective and environmentally responsible solution. It is simple to copy and apply in different settings to enhance waste management procedures. It is simple to empty the trash since the lid can be removed without harming the electrical components.
