SMART WASTE MANAGEMENT: IoT-ENABLED DUSTBIN WITH MULTI-SENSOR FUSION FOR AUTOMATED WASTE SEGREGATION AND REAL-TIME MONITORING

Abstract: This project presents an IoT-powered Smart Dustbin system designed to automate waste management and improve cleanliness in urban areas. It uses a combination of ultrasonic, infrared (IR), and metallic proximity sensors, all connected to a NodeMCU microcontroller, to monitor how full the bin is and to help sort different types of waste. The system can detect and separate metallic from non-metallic waste, using servo motors to guide each type into its own mini compartment. To keep things efficient, the dustbin is also equipped with GSM and GPS modules. These allow it to send SMS alerts when the bin is full and share its real-time location, helping city workers collect waste on time and plan better collection routes. All sensor data is sent to a web dashboard built with Python Flask, giving authorities the ability to monitor everything remotely. By combining intelligent waste segregation with location tracking, this system offers a smarter, more scalable solution for managing waste. It reduces the need for manual handling, encourages cleaner surroundings, and supports broader smart city goals. Overall, it’s a step forward in creating a cleaner, more efficient, and sustainable urban environment.
