A Review on IoT Based Solid Waste Management System

Abstract

Abstract: The proposed project presents an Automatic Solid Waste Management System using Arduino- based technology to separate waste into wet, dry, and metal categories. The system employs an IR sensor to detect the presence of waste, a moisture sensor to distinguish between wet and dry waste, and a proximity sensor for identifying metal waste. The Arduino UNO acts as the control unit, processing the inputs and controlling a servo motor to direct waste into the appropriate bin. This automated method ensures efficient waste segregation, reduces human effort, promotes recycling, and supports a cleaner environment. The system provides a smart, low- cost, and eco-friendly solution for modern waste management. This project can be implemented in public places, colleges, offices, and residential areas to improve cleanliness and reduce manual segregation. By integrating such automated systems, the burden on waste collectors can be minimized and the collected waste can be efficiently processed for recycling and composting, thus contributing to sustainable development. Furthermore, the project enhances public awareness regarding proper waste disposal, encouraging responsible environmental practices. It also demonstrates the potential of IoT and automation to solve real-life challenges. With further improvements and scalability, this system can serve as a reliable model for future smart cities.
