Efficient Arduino Nano based Dustbin Management System

Abstract

This paper proposed a smart dustbin using Arduino Nano, sensors, and servomotor which can work efficiently
even in remote places since there is no requirement of the internet or telephonic connectivity. In the proposed system, an
ultrasonic sensor measures the distance between the user and the dustbin. Then, the passive infrared sensor detects whether
the user is approaching the dustbin or not. If the user is approaching towards dustbin and the distance between the user and
the dustbin is less than 15 cm, the dustbin would open automatically for 30 seconds with the help of a hinge and servomotor.
In addition, another ultrasonic sensor determines the level of garbage inside the dustbin and indicates whether it is completely
or partially filled. Subsequently, the smart dustbin generates a sound from a buzzer and emits light from a light-emitting
diode if the dustbin is filled. The prominent advantages of the proposed smart dustbin are that it is very cost-effective, easy
to use, and will lead to a hygienic environment.
