Project Description:

The Smart Trash Can with Notifications is an IoT-based waste management system that detects the fill level of a trash bin and sends alerts when it needs to be emptied. It helps in automating waste collection, reducing overflow issues, and improving hygiene and efficiency in public or private spaces.

This project is highly applicable in smart cities, campuses, malls, offices, hospitals, and apartment complexes.

Technologies Used:

• Backend: PHP / Java / Node.js

• Frontend: HTML, CSS, Bootstrap, JavaScript

• Database: MySQL / Firebase / MongoDB

• Hardware:

  • Ultrasonic Sensor (for fill level detection)

  • Wi-Fi Module (ESP8266 / ESP32)

  • Microcontroller (Arduino / ESP32)

  • Power Supply

• Optional: GSM module for SMS alerts, buzzer, or LEDs

Key Features:

1. Automatic Fill Level Detection:

   • Uses an ultrasonic sensor to measure the distance between the trash and the lid.

   • Calculates how full the bin is (e.g., 80% full).

2. Real-Time Notifications:

   • Sends alert to the web dashboard or mobile app when bin is full.

   • Optional: Sends email/SMS to waste collectors or facility managers.

3. Live Dashboard Monitoring:

   • Visual interface to monitor multiple bins across locations.

   • Each bin shows current status: Empty, Half-Full, Full.

4. Historical Data Logging:

   • Tracks how frequently bins are being filled.

   • Helps in route and schedule optimization for collection teams.

5. Alert System:

   • Buzzer or LED light blinks when the bin is about to overflow.

6. Smart Analytics (Optional):

   • Charts showing waste generation trends.

   • Helps city planners or facility managers improve bin placement.
