This project aims to revolutionize traditional waste management using IoT technologies. Our smart waste management system optimizes waste collection processes, enhances environmental sustainability, and reduces operational costs.
Real-Time Monitoring: Utilizes ESP8266 microcontrollers and ultrasonic sensors to detect waste levels in bins.
Automated Operations: Arduino-controlled servo motors automatically open and close bin lids based on detected waste levels.
Data-Driven Optimization: Central monitoring station collects and analyzes data to plan optimized waste collection routes and schedules.
User-Friendly Interface: Web app provides real-time bin status updates and notifications for waste management authorities.

ESP8266 and Ultrasonic Setup:
-
Connection Setup: The ultrasonic sensor (HC-SR04) connects to the ESP8266 with VCC to 3V3, GND to GND, Trig to GPIO5 (D1), and Echo to GPIO4 (D2).
-
Distance Measurement: The ESP8266 sends a pulse via the Trig pin, measures the echo return time, and calculates the distance to the garbage.
-
Level Detection: The distance measurement determines the garbage level in the dustbin.
-
Data Transmission: The ESP8266 sends the garbage level data to a web interface and the Blynk app for real-time monitoring.
Arduino and Servo Setup:
-
Motion Detection: The ultrasonic sensor emits pulses and measures the time it takes for the echoes to return, calculating the distance to an object.
-
Threshold Check: If an object (e.g., a hand) is detected within a specified distance, the Arduino interprets this as motion near the dustbin.
-
Lid Opening: The Arduino sends a signal to the servo motor, causing it to rotate and open the lid of the dustbin.
-
Delay and Lid Closing: After a short delay (e.g., 5 seconds), the Arduino sends another signal to the servo motor to close the lid.
-
System Reset: The system returns to monitoring mode, ready to detect new motion and repeat the process.
