Smart Dustbin using Arduino
Introduction
In this article, we will be looking at how to make a smart dustbin using Arduino, an ultrasonic sensor, and an SG-90 servo motor. Let's start!
Β
Hardware Required
We will need the following components for making the smart dustbin
If you don't have any of the hardware then you can click on the required component name and buy it from our store.
1. Arduino Uno
Β
It is a development board used to do all the processing.
Β
2. Ultrasonic Sensor HC-SR-04
It is used as an object detection sensor. It is used to measure the distance of the object from the sensor.
3. SG-90 Servo
A Servo motor is used for moving the dust bin lid.
4. Jumper Wires
Used to do circuit connections between different components.
Β
Working Principle
Smart Dustbin works on the principle of object detection using an ultrasonic sensor.Β The ultrasonic sensor transmits sound waves. These waves get reflected whenever an object comes into the vicinity of the sensor. This generates an electrical signal which is used to open the dustbin lid.
Circuit Diagram
Make the connections as shown in the diagram below.
Program Code
Servo servo;
This creates servo object.
int trigPin = 5; |
The above lines assign trigger and echo pins of the ultrasonic sensor to 5 and 6 respectively. Servoβs PWM pin is connected to pin 9 of Arduino.
long duration, distance, average;
long averDist[3];
Β
These are the variables created for storing and processing data from ultrasonic sensor.
servo.attach(servoPin); |
servo. Attach (servoPin) - attaches the servo variable which we created initially to the servo pin, set trigger and echo pins as Output and Input respectively, close the lid of the dustbin by setting servo to 0 positions, and then detach the servo object.
Β Serial.println(distance);Β Β |
Measure function calculates the distance and average calculates the average of 3 distances measured by ultrasonic sensor.
Β if ( distance <= 30 ) { |
If the distance is less than 30 then the dustbin lid is opened by setting the servo to 180 position otherwise the dustbinβs lid is closed.

Frequently Asked Questions
1. How does smart dustbin work with Arduino?
The smart dust bin, powered by Arduino, is equipped with sensors to identify objects in close proximity. A signal is then transmitted to a servo motor, which unhinges the lid. The motor is programmed to shut the lid after a certain duration. Additional sensors can detect the bin's filling level and send alerts to users for emptying. This technology boosts waste management efficiency.
2. Is smart dustbin an IoT device?
Yes, a smart dustbin is an IoT or Internet of Things device that uses sensors, wireless connectivity, and cloud-based analytics to monitor and optimize waste management. It can detect the level of trash in the bin and alert waste management teams when it's time to empty it, improving efficiency and reducing costs. Smart dustbins can also help cities and organizations track their waste generation and recycling rates, ultimately contributing to more sustainable and cleaner environments.
3. Which sensor is used in smart dustbin?
The mystical smart dustbins use ultrasonic sensors to detect the presence of objects or beings, resulting in automatic lid activation. Furthermore, weight sensors conjure the ability to measure waste volume and alert owners of the need for disposal.
