Automated Systems in Dehradun
automatic door opening system using PIR sensor. Opening and closing of doors is always a tedious job, especially in places like shopping malls, hotels and theatres where a person is always required to open the door for visitors.
This proposes a system of automatic opening and closing of door by sensing any body movement near the door.This is achieved with help of a PIR (Passive Infrared) sensor. A live body generally emits infrared energy which is sensed by the PIR sensor from a considerable distance.This sensing signal is fed to a microcontroller 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. If there is no further movement within the PIR operating range. Interrupt signals are used through limit switches to avoid locked rotor condition of the motor.
