Project Summary

This project is a simple design of an automatic door opening system where the PIR sensor serves the primary input function and here Arduino UNO.

We have considered two feedbacks to this architecture when we implement an effective system, there can be a display unit for showing the number of persons entered in a particular room. We can use face detection through the camera for an automated attendance system.

Thus, we can conclude that this is a simple and low-cost architecture of automatic door opening system but has lots of benefits such as we can conserve energy, reduce human efforts, saving time, etc.

Project Objectives

Objective

• Accessibility: Since automatic doors can be opened without the use of

hands, they offer convenience to everyone even with baggage in both

hands or carrying a cart. Automatic doors are widely used in high traffic

places like commercial buildings, hotels, and public facilities to show care

and good customer service.

• Barrier-Free: Automatic doors provide excellent customer service by

allowing everyone enters easily, regardless of their age or physical

capabilities. In Japan, automatic doors for multi-purpose toilets are highly

recommended at public facilities such as stations and city offices.

• Energy-Saving: Automatic doors effectively contribute to energy saving

and reduce annual heating and cooling costs. Doors open only when

activated and automatically close so to eliminate the doors being left open.

They also prevent air-conditioning from escaping and outside air and dust

from entering.

• Hygiene Control: The hands-free operation of automatic doors offer a

optimal solution to hospitals and food factories where sanitation is

essential. An automatic door with an air-tight function can also prevent the entry

of dust and dirt by increasing the air pressure of the room, which is suitable

for operating rooms and other controlled environments.

Project Implementation Method

At these times, all human beings have a place of their own in which they keep

their property with the help of locks to limit the penetration of their personal

property or privacy, but there are many defects in these locks, such as easy

penetration poor security, and the difficulty of dealing with the lock-in one way,

which is the traditional key and there is no other way.

The second problem is the occurrence of errors on the part of the human being

so that the loss of the key is very likely, also carrying many keys that expose

them to loss or ease of theft, also you can forget to close the lock, and here the lock cannot  be  closed  by  itself  because  it  is mechanical  and  does  not 

depend on Electromechanical. 

Benefits of the Project

Now more and more hotels, shopping malls, and banks use automatic doors, but

while automatic doors are convenient for people, what are the advantages and

disadvantages? The following is a comparison between automatic doors and

revolving doors. The main advantages of automatic doors: can realize automatic

induction switch, pedestrians can realize non-contact switch, automatically close

when no one is there, separate the convection of indoor and outdoor air, and have

the effect of energy-saving and heat preservation, wind and sand prevention, and

can be free with access control Connected to realize real door control automation

and intelligent door control. It is not restricted by installation site and space. It is

suitable for installation in indoor and outdoor, offices, buildings, stores, exhibition

halls and various occasions. Ample opening space and convenient access.The

advantages of manual revolving doors: it can achieve true isolation between

indoor and outdoor, whether it is when pedestrians enter and rotate, or when

they are still stationary, and the indoor and outdoor isolation is maximized in time and

space. Manual revolving doors do not require a power supply, There is energy

saving, real energy-saving, and environmental protection, while the operation is

safe and stable, firm, trouble-free, and long-term use without maintenance costs.

Technical Details of Final Deliverable

Working of Automatic Door Opener System

The working of the Automatic Door Opener System using Arduino and PIR

The sensor is very simple. This project can be considered as an extension of Arduino

PIR Sensor Tutorial and Arduino L298N DC Motor Control Tutorial.

When the PIR Sensor detects any motion of a person, its Data OUT Pin will

become HIGH. As this pin is connected to the Arduino, it will see this HIGH

Signal and understands that there is a person approaching the door. Arduino then

immediately activates the L298N Motor Driver module to open the door. After

some time (about 2 to 5 seconds in this project), the Arduino will 

activate the Motor Drive to close the door.

Working Principle:

The infrared sensor has its detecting area. The multi zonal Fresnel lens array is

associated covers the pyroelectric transducer. This lens is a Plano-convex lens that

is designed to collect infrared radiation from the different spatial zones.

Fresnel lenses are made up of material that can transmit the infrared range of SuM to

14um. This lens does not view the space in a continuous fashion, the detection

pattern of the sensor is fan-shaped. It views as discrete beams or cones. The gap

between the cones increases with the distance and it is inversely proportional to

the sensitivity of the sensor. The PIR sensors have two pins and 2 are

activated when a radiation source passes in the field of view. Pins are wired a
