Create an IoT Smart Waste Management System

Components Required

• Microcontroller: ESP8266 or ESP32
• Ultrasonic Sensor: HC-SR04
• Load Cell: for weighing waste
• Wi-Fi Module: integrated in ESP8266/ESP32
• Power Supply: Battery or USB
• Jumper Wires and Breadboard
• Data Dashboard: Web or mobile application

Overview

This project involves creating a smart waste management system that uses ultrasonic sensors to measure waste levels in bins and communicate this data over the internet. The data can be monitored in real-time through a web interface, providing insights for efficient waste collection.

Steps to Implement

1. Set Up the Microcontroller

   Connect the ESP8266/ESP32 to your computer and install the necessary libraries in the Arduino IDE.

2. Connect the Ultrasonic Sensor

   Wire the HC-SR04 to the microcontroller to measure the distance to the waste level.

3. Connect the Load Cell (Optional)

   If weighing waste, connect the load cell to the microcontroller using an HX711 amplifier.

4. Write the Code

   Develop the Arduino sketch to read sensor data and send it to a server.

   
   #include 
   #include 
   
   #define TRIGGER_PIN  D1
   #define ECHO_PIN     D2
   #define MAX_DISTANCE 200
   
   const char* ssid = "YOUR_SSID";
   const char* password = "YOUR_PASSWORD";
   
   NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE);
   
   void setup() {
       Serial.begin(115200);
       WiFi.begin(ssid, password);
       // Connect to WiFi...
   }
   
   void loop() {
       delay(1000);
       float distance = sonar.ping_cm();
       // Send data to server...
   }
                       

5. Set Up the Web Server

   Create a web server to receive and display the data from the microcontroller.

6. Monitor Data

   Access the web interface to monitor the waste levels in real-time.
