Smart Dustbin System Using IR and Wet Sensors with Servo Motor Control

This project presents a smart dustbin system that utilizes an IR sensor, a wet sensor, and a servo motor to automate waste sorting. When an object is detected near the dustbin using an IR sensor, the system checks if the object is wet or dry using a wet sensor. Based on the result, the servo motor positions the lid to either the "wet" position (40°) or the "dry" position (120°). If no wet material is detected, it assumes the object is dry and opens accordingly. After 2 seconds, the servo motor returns to its normal standby position (83°). This system improves hygiene and supports basic waste segregation at the source.
