This document describes a smart dustbin system that uses sensors and IoT technology to monitor garbage levels in public dustbins. An ultrasonic sensor measures the garbage level in the dustbin and an ESP8266 WiFi module sends this data via the internet. When the dustbin reaches 70% capacity, an SMS alert is sent to the local authorities. This notifies them to empty the overflowing dustbin and maintain cleanliness. The system aims to optimize waste collection, reduce costs and pollution from frequent emptying of partially filled dustbins.
