Introduction

In today's quest for smart solutions, we delve into understanding the circuit diagram, code explanation, and associated products for creating a Smart Dustbin. This technology leverages sensors such as ultrasonic sensors to automate the opening and closing of the dustbin lid based on proximity.

Circuit Diagram

The circuit diagram of a Smart Dustbin includes the following key components:

Ultrasonic Sensor: Detects the presence and distance of an object.
Servo Motor: Rotates to open/close the dustbin lid.
Microcontroller (like Arduino): Processes sensor input and controls the servo motor.
Power Supply: Often a battery connected in saver mode.

The connection involves attaching the ultrasonic sensor to the microcontroller, which in turn connects to the servo motor. The whole setup is powered by a battery that has saver mode enabled to conserve energy.

Code Explanation

Below is a simplified version of the pseudocode:

#include <Ultrasonic.h>
#include <Servo.h>

Ultrasonic ultrasonic(12, 13);   // Trigger and Echo pins of the Ultrasonic Sensor
Servo servo;                     // Servo motor object

const int thresholdDistance = 30; // Distance in cm to trigger opening

void setup() (
  servo.attach(9);               // Pin connected to the servo
  servo.write(0);                // Initial position of the servo
)

void loop() (
  int distance = ultrasonic.readDistance();
  
  if (distance <= thresholdDistance) {
    servo.write(180);            // Open the lid
    delay(2000);                 // Wait for 2 seconds
    servo.write(0);              // Close the lid
  ) else (
    // Do nothing
  )
  
  delay(500);                     // Delay for stability
}

This code reads the distance from the ultrasonic sensor. If the distance is within 30 centimeters, the servo motor rotates 180 degrees to open the lid and then closes it after 2 seconds.

Products and Software Used

Product Modules: Ultrasonic sensors, servo motors, microcontrollers (Arduino), batteries in saver mode.
Software: Arduino IDE for coding and uploading the program to the microcontroller.

Real-life Applications

Such smart systems can be implemented in various public and private spaces for improving hygiene and convenience. The system can be extended to work with more complex IoT setups, integrating with other smart home systems and providing data analytics.
