Smart Garbage Segregation and Level Monitoring System

With the rapid urbanization and growing population, effective solid waste management has become an increasingly critical challenge. Improper segregation of waste at the source results in inefficient recycling and disposal processes, leading to increased environmental and health hazards. This paper proposes a cost-effective and scalable system for automatic waste segregation and bin-level monitoring using microcontroller-based IoT technology. The system segregates waste into three categories: dry, wet, and metal, using IR, moisture, and metal sensors. A NodeMCU ESP8266 microcontroller processes sensor data and activates servo motors to direct waste into the appropriate bin. Additionally, ultrasonic sensors monitor bin levels, and status updates are wirelessly displayed via a local Wi-Fi webpage. The results demonstrate reliable classification, timely alerts, and significant reductions in manual effort, enhancing hygiene and contributing to sustainable urban waste management.
