As our population continues to grow, so does our problem with pollution. Garbage can be seen piling up in urban and rural areas, leading to a severe problem of land pollution. Dustbins, Garbage bins, Trash Cans, or whatever you call them, are small plastic or sometimes metal containers used to store trash or waste temporarily.
They are usually spotted at homes, offices, streets, parks, etc., to accumulate junk. In some areas, the government has placed waste containers for public use, which is the only way to overcome pollution, as it causes many problems. Still, whatever the case is, this is the only solution to keep the garbage stored. This project is constructed with a simple system called Smart Dustbin using Arduino, Ultrasonic Sensor, and Servo is also inserted, which opens the head of the dustbin automatically without human interaction.
Smart Dustbin Technology
The Smart Dustbin is a sensor-based circuitry that works automatically. It opens up when it detects the presence of garbage nearby and closes automatically after a few seconds. This project uses Arduino technology, and the components used include the HC-04 ultrasonic sensor and the servo motor. It is a simple and easy technique that costs around $2.
“Our aim was to create a solution to land pollution that is not only efficient and cost-effective but also easy to use for everyone. We are proud of the progress we have made so far and are excited to see the impact it will have on the environment.”
This innovation is a game-changer for households, offices, and city areas with a high population rate. With the Smart Dustbin, there is no need for human interaction to open it up by pushing its button with the feet. Instead, it is designed to detect any human legs, hands, or objects near it and generates a signal to open up automatically. This ensures the dustbin is always ready to receive waste, making it more efficient and convenient.

Smart Dustbins using Arduino: Revolutionizing Waste Management with Ultrasonic Sensors and Servo Motors
In an era where technology is taking over every aspect of our lives, it is no surprise that it has found a way to revolutionize waste management. Smart Dustbins using Arduino has become the new solution with the rise of environmental concerns and the need for efficient waste disposal.
“The hands-free experience provided by these dustbins eliminates the need for human interaction, which is critical in a post-pandemic world.”
The dustbin is equipped with an Ultrasonic Sensor and Servo Motor that detects and open the lid automatically, making it a hands-free experience. Ultrasonic sensors and servo motors have become critical components in electronic engineering. The technology behind Smart Dustbins is based on object detection using Arduino, a simple and easy-to-implement device.
“Smart dustbins are a step towards creating smart cities and promoting sustainability.”
The same technology is used in Object Avoiding Robots, where an intelligent car detects an object and changes its position automatically to avoid a collision. In this project, the Ultrasonic Sensor is placed on top of the dustbin, and when it detects an object, like a human hand, it triggers the Arduino to open the lid.
“This technology not only makes waste disposal more efficient, but it also helps to reduce the spread of diseases,”
The implementation of Smart Dustbins using Arduino has seen significant growth in recent years, with governments and organizations investing in these waste management solutions. With the advancement in technology, it is expected that Smart Dustbins will become a household name and a key player in the fight against pollution.
How the Smart Dustbin Works
Once set up and programmed, the smart dustbin works efficiently to make waste disposal hassle-free. After all the necessary connections have been made and the code uploaded to the Arduino, power is supplied to the circuit. The ultrasonic sensor continuously works to detect any object nearby, measuring the distance to check if it is less than the predefined value. If an object is detected, such as a hand or leg of a human being or any other thing, a signal is sent to the motor. The motor is activated, and the head of the dustbin, which is attached to the servo motor, is opened by the Arduino. After a few seconds, the head of the dustbin will automatically close because of the predefined value that can be easily changed. This process ensures that waste disposal is made easy and convenient for everyone.
Building a Smart Dustbin: Required Components and Step-by-Step Process
Smart Dustbins are the future of waste management, and the best part is that they are easy to build using a few essential components. These components are readily available in the above given links, making building your own Smart Dustbin easy.
Once you have all the necessary components, the next step is to start building. The procedure category explains the step-by-step process, where you will learn how to assemble the components and program the Arduino to open the dustbin lid automatically when a hand is detected. With this project, you can contribute to keeping the environment clean and safe, one step at a time.

The circuit diagram is shown below, and the wiring is also discussed in the procedure section.
Note: Step by step procedure is given below. Make sure to have the same components above to make a smart dustbin.
Code Of Arduino:
//define Pins
#include <Servo.h>
Servo servo;
int trigPin = 9;
int echoPin = 8;
// defines variables
long duration;
int distance;
void setup()
{
servo.attach(7);
servo.write(0);
delay(2000);
// Sets the trigPin as an Output
pinMode(trigPin, OUTPUT);
// Sets the echoPin as an Input
pinMode(echoPin, INPUT);
// Starts the serial communication
Serial.begin(9600);
}
void loop()
{
// Clears the trigPin
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
// Sets the trigPin on HIGH state for 10 micro seconds
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
// Reads the echoPin, returns the sound wave travel time in microseconds
duration = pulseIn(echoPin, HIGH);
// Calculating the distance
distance= duration*0.034/2;
// Prints the distance on the Serial Monitor
Serial.print(“Distance: “);
Serial.println(distance);
if ( distance <= 25 ) // Change Distance according to Ultrasonic Sensor Placement
{
servo.write(0);
delay(3000);
}
else
