Project Description:

The Smart Garbage Bin with Alerts is an IoT-enabled waste management solution that monitors the fill level of public or private garbage bins in real time. When the bin reaches a certain threshold, the system automatically sends alerts to municipal authorities or facility managers, optimizing garbage collection and preventing overflow.

This project is ideal for smart cities, public areas, educational campuses, and corporate parks, promoting cleanliness and automation.

Technologies Used:

• Backend: PHP / Java / Node.js

• Frontend: HTML, CSS, Bootstrap, JavaScript

• IoT Microcontroller: ESP8266 / ESP32 / Arduino

• Sensors: Ultrasonic Sensor (HC-SR04) to measure garbage level

• Connectivity: Wi-Fi / GSM / LoRa (for remote locations)

• Database: MySQL / Firebase

• Optional Add-ons: GPS Module (for bin location), Load Cell (weight monitoring), Camera Module (visual confirmation)

Key Features:

1. Real-Time Fill Level Monitoring:

   • Ultrasonic sensor detects how full the bin is.

   • Bins are monitored 24/7 with live data updates.

2. Smart Alert Notifications:

   • Sends email/SMS/app alerts when the bin is 75%, 90%, or 100% full.

   • Prioritizes collection based on criticality.

3. Web-Based Dashboard:

   • Visual map showing bin locations and their status (empty, half, full).

   • Data presented using progress bars, color codes, and real-time updates.

4. Historical Data and Analytics:

   • Track waste patterns by day/week/month.

   • Helps schedule optimal pickup times and locations.

5. Power Efficient Design:

   • Low-power sleep mode with wake-on-sensor trigger.

   • Solar panel integration (optional).

6. Location Tracking (Optional):

   • GPS shows bin location for routing waste collection vehicles.

7. User Interaction (Optional):

   • Public-facing web app to report overflowing bins manually.

   • QR code on bin for scanning and submitting complaints.

System Workflow:

1. User or trash is disposed of into the bin.

2. Ultrasonic sensor continuously measures distance from bin lid to garbage top.

3. Microcontroller calculates fill level and sends data via Wi-Fi/GSM.

4. Backend receives data, updates dashboard, and checks for alert conditions.

5. Notifications are sent if thresholds are met.

6. Collection teams respond to full-bin alerts efficiently.
