Autonomous Door Open and Close System

Description

In modern era, opening and closing of doors is always a tedious job, especially in places like shopping malls, hotels and theaters where a person is always required to open the door for visitors. This project proposes a system of automatic opening and closing of door by sensing any body movement near the door. This is achieved with help of either sensor or switch control as per requirement. The door open/close signal is fed to a micro controller to operate a door motor through motor driver IC. When a body approaches within the operating range of the sensor, it sends a logical command to open the door. The door automatically closes with a fixed time delay.
