How to make Smart Dustbin with IoT using Blynk and ESP32

In this Article, we learn about how to make Smart Dustbin with IoT using Blynk and ESP32.

In the Last post, we learned about how to make Wireless ESP32 Analog Sensor Monitoring System with LCD Display and Web Interface.

Let’s dive into

Components Require:

ESP32 board
Ultra Sonic Sensor (HC-SR04)
IR Sensor
Servo Motor (SG90)
Step down power supply (12V to 5V)
Jumper wires

Circuit Diagram:

How it Works:

Smart Dustbin with IoT using Blynk and ESP32 combines hardware components and software to create a system that allows remote monitoring and control of a dustbin. The Blynk app acts as a user interface, and the ESP32 handles the sensor data and motor control, with communication facilitated through the Blynk Cloud.

The ESP32 microcontroller is the brain of the system. It’s programmed to read data from the ultrasonic sensor, which measures the distance from the top of the trash to the sensor.

A servo motor is connected to the dustbin’s lid. The ESP32 controls the servo motor to open and close the lid.
