This document describes a proposed smart garbage bin system using IoT technology. The system uses ultrasonic sensors to measure garbage levels in bins, an AVR microcontroller to process sensor data and trigger alerts, and a GSM modem to notify authorities when bins reach a threshold level. The system aims to efficiently manage waste collection and avoid overflowing bins. Data from sensor nodes attached to each bin is sent to the cloud for analysis and monitoring of bin fill levels across the city. The smart bin system is expected to improve waste management by automating the collection process.
