ABSTRACT

The project is titled design and construction of an automatic gate opener using infrared. 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 project proposes a system of automatic opening and closing of door by using remote. The remote sensor transmitter emit infrared radiationÂ from a considerable distance and sends it to the receiver, commanding the receiver to either open the gate or to close it. This sensing signal is fed to a controller to operate a door motor through motor driver IC.

The remote sensor sends a logical command to open the door. The door automatically closes with a fixed time delay.

Â CHAPTER ONE

1.1Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â INTRODUCTION

An automatic gate opener using infrared involves open and closing a door using remote sensor: The most common single-technology sensor operated door uses passive infrared (PIR) energy to recognize the movement of heat in a protected space, and the sensor compose of the transmitter and the receiver.

This project proposes a system of automatic opening and closing of door by pressing a remote when we want the door to be close and vice-versa. This is achieved with help of a PIR (Passive Infrared) sensor. When the remote is pressed the sensor emits infrared energy which is been received by the receiver from a considerable distance. This sensing signal is fed to a controller to operate a door motor through motor driver IC.

When the remote is pressed, it sends a logical command to open or close 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.

1.2Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â OBJECTIVE OF THE STUDY

The main objective of this work is to design a an automatic gate opener using infrared for homes, that is,Â to open and closing a door using infrared.

Â 1.3Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â SIGNIFICANCE OF THE PROJECT

Remote automatic doors operate with the help of sensors. Sensors do exactly what they sound like theyâ€™d do: they sense things. There are many different types of sensors that can sense different types of things, such as sound, light, weight, and motion.

For example, some automatic doors operate when theyâ€™re triggered by sensors that sense weight. These weight sensors might be disguised in a rubber mat in front of the door. When you step on the mat, the sensors send a signal to the automatic doors that tells them to open.

Other automatic doors operate on optic or motion sensors. These sensors might be mounted above a set of automatic doors or built on the top or the sides of the frame of the automatic doors.

When these optic or motion sensors sense motion nearby, they trigger the automatic doors to open and then close. This is why, when you approach a set of automatic doors, they will open as soon as you get close enough to activate the sensors.

Automatic doors have many useful purposes, which is why you can find them in many different types of locations. From supermarkets to airports and many types of large buildings, automatic doors make it easier for people to get into and out of buildings. They are especially helpful for people who are handicapped.

Similar to revolving doors, automatic doors also help to save energy, since they limit the amount of time that doors are open to only those times people are entering or exiting a building. And if youâ€™ve ever shopped until your hands are full of bags.

This automatic gates do not need any physical effort to open or close. It has sensors, once the sensor senses the presence of human being it opens.

Automatic gates are durable, strong and can be available in customized sizes. It is a first security system of your property, giving you a sense of security. Automatic gates Â provide a security to your kids who can play safe inside the property without any interference of outsiders.

It is very convenient to enter and leave the automatic gates. You can activate even you are 20-30 metres away from it. No longer have you had to come down from your cars to open your gates.

1.4Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â LIMITATION OF THE PROJECT

The establishment of electric entryways involves a good amount of money related use. This ranges from buying the gate to services for installation. to paying for the administration of the installers.
Most of the companies give free after sales services to a certain period of time. However, it is super costly after the time period is lapsed.
In case of power failure, malfunctioning system or anyone trapped inside your property, can cause inconvenience.

1.5Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â APPLICATION OF THE PROJECT

Remote control gates aren’t just used for home security only. In industrial fields, they are used on assembly lines to keep track of the number of products and to shut down dangerous equipment if a person gets too close.

Here are a few other ways PIR sensors are used:

To open and close automatic Doors
To turn on and off automatic water faucets and toilets
To turn on lights when a person enters a room
To control ATM displays
At automatic ticket gates
For some parking meters

PIR sensors aren’t just an additional feature of a security systemâ€”they are essential. Without sensors, there wouldn’t be a way to detect intruders.
