Smart Dustbin Project

Description

Some dustbins have a foot pedal to open their lid. It is very important to close the bins with a lid to maintain hygiene and odor. The smart dustbin that we proposed has a lid that opens and closes automatically.

You don’t have to touch the dustbin to open it whenever you come close to it, the sensor detects you and automatically opens the lid. After a few seconds if the sensor doesn’t detect someone near it then the lid will be closed automatically.

We are using an ultrasonic sensor that transmits the ultrasonic waves and receives the waves when they come back by hitting any object. so when the person detects in front of the smart dustbin it sends some signal to the Arduino which we are using as a Controller in this project.

so now the Arduino gets the data and analyzes the data for further processing so that the dustbin can operate well.

now, we will explain how the Arduino analyses the data. the ultrasonic sensor sends the received signal to the Arduino and Arduino calculates the distance by the duration of soundwaves come back.

In smart dustbin using Arduino according to the distance, we make some conditions in the code. like if the distance between the person and the dustbin is less than 20 centimeters then the Arduino will send a command to the servo motor to rotate 90 degrees from its initial position which causes the lid to open and after the interval of 10 seconds, the lid well automatically close.
