7. ABSTRACT
Opening and closing of doors have always been a tedious and boring job,
especially in places like; hotels, shopping malls, theaters, etc. where a person is
always required to open and close the door for visitors. This human involvement can
be avoided by automating the process using different sensors like infrared, pressure,
ultrasonic, laser etc. In this paper, automatic door control system using Arduino
microcontroller was designed. The system combines ultrasonic sensor, servo, and
Arduino to achieve the desired goal.

TABLE OF CONTENT

9. The market for automated doors is growing and becoming more
specialized. The type of product that fits best with a particular application is
determined by frequency of operation, speed of operation required, new
versus existing construction, traffic flow and cost. Automatic doors are a
normal feature in many commercial buildings and infrastructures such as
shopping centers and airports, as well as in industrial environments such as
factories. Although they come in variety of types, including sliding, swing,
folding, etc. they all need to conform to the highest standards of safety.
INTRODUCTION

10. 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. So, that's
why we are motivated to making this project
MOTIVATION

11. The aim of this project is to design an Automatic Door Opening system using
Arduino UNO, in which the door is automatically opened and closed by
detecting the movement of a person. Before going to the working of the project,
let us see the basic requirements of the project.
● When a person approaches the door through the doorway, the system must
detect the person and open the door automatically.
● The door should stay open as long as the doorway is not clear i.e. as long as
the system detects a person.
● Once the doorway is cleared, the system must close the door automatically
and wait for the next person.
OBJECTIVE

12. Arduino UNO is a microcontroller board based on the ATmega328P. It has
14 digital input/output pins (of which 6 can be used as PWM outputs), 6
analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack,
an ICSP header and a reset button. It contains everything needed to support
the microcontroller; simply connect it to a computer with a USB cable or
power it with a AC-to-DC adapter or battery to get started.

Ultrasonic Distance Sensor
Ultrasonic Sensor HC-SR04 is a sensor that can measure distance. It emits an
ultrasound at 40,000 Hz (40kHz) which travels through the air and if there is an
object or obstacle on its path It will bounce back to the module. Considering the
travel time and the speed of the sound you can calculate the distance.
The configuration pin of HC-SR04 is VCC (1), TRIG (2), ECHO (3), and GND
(4). The supply voltage of VCC is +5V and you can attach TRIG and ECHO pin to
any Digital I/O in your Arduino Board.

19. Ultrasonic Distance Sensor distance measurement:
THEORY
Sound travel in air 340 m/s,
It’s mean that ,
1’s sound travel in air = 340m, 34,000cm.
1µS ——————— = 34,000/1000000 [1µS = 10^-6s]
So, sound travel in air = 0.034cm/ µS
and we pick the duration (microSecond) of echo pin high using pulseIn(pin, HIGH)
Distance = (duration x Speed of sound in air)/2
more in next slide

20. Ultrasonic Distance Sensor code syntax:
THEORY
#define echoPin 2
#define trigPin 3
long duration;
int distance;
void setup() {
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
}
void loop() {
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance = duration * 0.034 / 2;
}

21. Servo motor
THEORY
Servo motors have three wires: power, ground, and signal. The power wire is
typically red, and should be connected to the 5V pin on the Arduino board.
The ground wire is typically black or brown and should be connected to a
ground pin on the board. The signal pin is typically yellow or orange
connected to A/D pin on the board

22. Basic Code syntax of Servo motor
THEORY
#include <Servo.h>
Servo myservo;
int pos = 0;
void setup() {
myservo.attach(9);
}
void loop() {
for (pos = 0; pos <= 90; pos += 1) {
myservo.write(pos);
delay(15);
}
for (pos = 90; pos >= 0; pos -= 1) {
myservo.write(pos);
delay(15);
}
}

RESULTS & DISCUSSION

30. The advantage door automation system -
ADVANTAGES
1. 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 at high traffic places like commercial buildings, hotels and public facilities to show
care and good customer service.
2. Automatic doors provide excellent customer service by allowing everyone enters easily,
regardless of their ages or physical capabilities. In Japan, automatic doors for multi-
purpose toilets are highly recommended at public facilities such like stations and city
offices.
3. The hands-free operation of automatic doors offer a optimal solution to hospitals and food
factories where sanitation is essential. Automatic door with airtight 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.

31. CONCLUSION
In this lab project we are able to design ‘Door automation System’ . And the
theoretical knowledge programming code is successfully run in practical and
there have no any error. And we are success in project.
