This document describes the design and implementation of a smart dustbin system using IoT notifications. The system uses ultrasonic sensors placed above trash bins to detect garbage levels and send this data to an Android application via an Arduino microcontroller and WiFi module. When a bin reaches a certain fill level, a notification is sent to alert authorities to empty it. The system aims to help maintain cleanliness and avoid hazardous situations by automating waste collection. It monitors bin levels and notifies staff in real-time using low-cost hardware and an IoT approach.
