This project presents an IoT-based system for optimizing waste collection and monitoring.
It leverages sensors, cloud integration, and data analytics to provide real-time visibility into waste bin status, enabling more efficient collection and reducing environmental impact.
- Monitor waste levels and weight in real time.
- Notify collection teams automatically when bins are full.
- Optimize collection routes and schedules.
- Support scalable deployment for various environments (cities, campuses, corporate sites).
- Ultrasonic Sensor: Measures the waste level.
- Load Cell Sensor: Measures the weight of the waste.
- Microcontroller (ESP8266 / NodeMCU): Collects and processes sensor data.
- Wi-Fi Communication (ESP8266): Sends sensor data to the cloud.
- HTTP Protocol: Ensures secure and reliable communication.
- Cloud Platform (Firebase): Stores bin data and manages notifications.
- Web Dashboard: Displays bin status and analytics for administrators.
- Notification System: Alerts collection teams when bins reach threshold levels.
- Data Analytics: Provides insights into waste generation trends.
| Component | Function | Quantity | Notes |
|---|---|---|---|
| Ultrasonic Sensor | Detects waste level | 1 per bin | Mounted at top |
| Load Cell | Measures waste weight | 1 per bin | Under bin base |
| ESP8266 (NodeMCU) | Processes and transmits data | 1 per bin | Wi-Fi enabled |
| LCD 1602 (I2C) | Local display for bin status | Optional | Real-time info |
- Microcontroller firmware: Reads sensor data and transmits to cloud.
- Cloud service (Firebase): Real-time database and hosting.
- Web application: Monitors bin states and generates alerts.
- Sensors detect waste level and weight.
- ESP8266 processes data and sends it via HTTP to Firebase.
- Firebase updates the dashboard and triggers notifications if thresholds are exceeded.
- Authorized users access data through the web interface.
