Key Features

1. Automatic Connectivity:

Establishes a Bluetooth connection with waste collection trucks when they are within a range of 10–15 feet.

2. Data Logging:

Tracks the collection frequency and quantity of garbage for daily, weekly, and monthly records.

3. Overfill Detection:

Sensors monitor the dustbin's fill level and send alerts when it's nearing capacity.

4. Smart Recordkeeping:

Logs collection events and syncs with a central waste management system.

5. Mobile Alerts:

Notifies the collection team of full dustbins for optimized route planning.

2. Bluetooth Module (e.g., HC-05 or BLE 5.0):

Enables communication with collection trucks.

3. Ultrasonic Sensors:

Detects the fill level of the dustbin.

4. Power Supply:

Rechargeable battery with solar panel integration for sustainable energy.

5. Data Storage:

Embedded memory or cloud storage for logging collection records.

6. LED Indicators:

Displays the operational status and alerts for overfill.

7. Weatherproof Enclosure:

Mechanism

1. Setup and Connectivity:

The dustbin is equipped with a Bluetooth module that continuously scans for authorized collection trucks.

2. Fill Level Monitoring:

Ultrasonic sensors measure the fill level and send the data to the microcontroller.

If the dustbin is full, an alert is sent to the central system and nearby collection trucks.

3. Data Transmission:

When a collection truck is within range, the dustbin transmits data like:

Current fill level.

Last collection date and time.

Dustbin ID for tracking.

4. Record Logging:

Data is stored locally and synced to the cloud for generating daily, weekly, and monthly reports.

5. Post-Collection Updates:

After the truck collects the garbage, the system resets the fill level and logs the event.

Benefits to Community

1. Efficient Collection Routes:

Alerts help trucks prioritize full dustbins, reducing unnecessary trips.

2. Reduced Overflow Issues:

Timely alerts prevent garbage overflow in public spaces.

3. Accurate Data Records:

Ensures accountability and helps optimize waste management systems.

4. Sustainability:

Solar-powered system reduces reliance on traditional energy sources.

5. Scalability:

Can be implemented in urban, suburban, and rural areas.
