Movement Sensed Automatic Door Opening System
PROJECT DESCRIPTION

The main aim of this project is to avoid manpower for closing and opening the doors in places such as shopping malls, hotels and theaters using a PIR sensor that senses anybody's approach or movement near the door.

The proposed system uses a microcontroller of the 8051 family and a rectified-power supply. In this system, a PIR sensor is interfaced to the microcontroller through a transistor for sensing anyone who approaches within the operating range. The door is controlled by the motor which is connected to the microcontroller through a motor driver.

In this project, the PIR sensor detects anyone approaching within the operating range. Whenever any person comes near to the door, the sensor detects the body movement, and then sends the logic signals to the microcontroller to operate the door automatically by the motor with a fixed time delay. 

This project in future can be implemented by integrating with counting arrangement with EEPROM to keep a record of entry and exit of people.

Q & A
Q:  What is the family of microcontroller used?
A:  Microcontroller from 8051 family is used.
Q:  What is PIR?
A:  A PIR sensor(passive infrared sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.
Q:  How is a door demonstrated in this project?
A:  CD loader is used as a sample used to demonstrate an actual door.
Q:  Where is it used?
A:  It is used at shopping mall, theaters, hotels, where automatic door opening is required
