Introduction:

This is the Final Year Project for Bachelor Degree in Software Engineering, In this Project we are using the Internet of things to create a Smart Parking Assistance System, In this system we are using IR Sensors, Arduino UNO Board and connect that Arduino Board with a website and Android Application. The purpose of this application to provide help to user to park their cars save time along the way.

There are four main components,

1. Website
2. Android Application
3. Database
4. IOT Hardware

Website:

The website is codded using PHP, HTML, CSS and Java Script, there is a database that is designed in SQL.

Web Pages:

The Web Pages are coded in php and javascript, The php is used for thr creating the website and javascript is used for the connection between the website and IOT parts.

PHP Pages:

There are total 11 web pages whcih are coded in php, HTMl and CSS.

1. db_conn.php

   This is part of the website that is responsible for the connection with the database. This the connection phase, The code for connection can be found in this file.

2. delete.php

   This file contain the code for delete the user profile from database.

3. display.php

   This file will fetch the user data and the data will be displayed in the form of a table.

4. home.php

   This file is the dashboard, After your are logged into the system, this home pages will be displayed.

5. login.php

   This file contain the Login form, you have to login into the system before you can View any data or make modification.

6. logout.php

   This file is logout, and the sessions, The session will help if you are logged out from the system then you can not go back by pressing the back button, The session can not allow that.

7. signup.php

   This is the page where admin or the manager will add more user so that they access the application.

8. update.php

   This is the pages where the admin or the manager can update the user profile.

9. viewstatus.php

   This is page where the live detection of parking will be displayed, The result from the hardware will be placed in this web page.

10. index.php

    This is the min running pages, The program will execute when index.php is called.

11. styles.css

    This is a file that will contain all of the css code for the website.

All of the above are php based website but we are also using HTML and CSS to design the website.

Hardware:

In this Project we are using Electronic Parts to get the signal, All of the parts which are used are stated bellow:

1. IR Sensor
2. Arduino UNO Board
3. Bread Board
4. Male to male Cables
5. Male to Female Cables

Each of the Parts are put together to form one unit, The picture of the unit is bellow:

The above image shows the whole working of the system. and each Sensor is color coded.

IR Sensor:

There are three pin in each sensor one is Ground, second is Power and the third one is Code line.

On a Sensor there are three labels

1. GNN

   GNN present ground line

2. OUT

   OUT line present Code

3. VCC

   The VCC line Represent Power Line

Color Code list for Sensors:

• Sensor 1:

  Code Line Color: Orange

  Pot number:  3

  Power Color:  White

  Ground Color: Green

• Sensor 2

  Code Color Line: Red

  Port number: 4

  Power Color:  White

  Ground Color: Green

• Sensor 3:

  Code color: Yellow color

  Port Number: 5

  Ground: Yellow

  Power: White:

  Ground Color: Green

• Sensor 4:

  Code color: Blue

  Port number: 7

  Power Color:  White

  Ground color: Purple

Power For the Sensor:

In the UNO Board there are two power point, 3.5 Volt and 5 Volt Power.

The system is Powered by 5 Volt point.

Connection Hardware with Website:

• The connection between website and the hardware is done using the javascript. The problem with Arduino is that it can not connect to the website directly so we need a server and the server is designed in javascript, using a framework called Node js.
• Using Node Js we are using two libraries 1. Socket.io and 2. serialport
• Using both Libraries we can connect to the UNO board. The name of the file is called server.js, The server will run at the port of 3000.

Database:

The database is designed in SQL and there are total 3 tables

1. manager
2. User
3. Login

Manager:

The manager table contain different Attributes such as

1. email
2. name
3. password
4. Date of birthday.

The manager will login into the system using Email and Password.

The default Login detail are:

Manager_email: 99marafay@gmail.com

Manager_password: 19march1999

User:

The user table contain same as attribute as the manager.

The user can login into the system using the user_email and user_password.

Required Software to Install:

There are a couple of software that are required to be installed for the application to run.

1. Xampp
2. Vs code
3. Node js
   1. npm i -s serialport
   2. npm i -s socket.io
4. Arduino IDE

Process to Start the Application:

In Order to run the application, you need to install application. Check The Required Software Section to install the application. Once all of the application are Installed then download the code from the github by pressing the button “Download ZIP”

and the file will start to download.

1. Once File is Downloaded, Unzip the File.
2. Once unzipped then copy the folder to the directory in Xampp\hdocs
3. Once the file are in placed then open xampp control Pannel and then start the sql server.
4. Once the server is running open the Vs code
5. Once VS code is Opened then open the code folder in the VS Code.
6. Once Opened then open the Server.js file in VS code.
7. In the bottom provide the path of the view_parking spot and change the port number of which can be provided when Arduino IDE.
8. Connect the UNO board with the computer.
9. You can find the port number in tools section and then select port, copy the port number.
10. Then change the port number in the server.js.
11. Once the port number and the file for ver-parkingstatus is set then you need to run the server
12. Inorder to Run the server enter the following coomand in the terminal which is in the vs code “node server.js”
13. The server will start to run.
14. Once the server is running the enter the following URL in the broswer to upload the database so that website can work properly.
15. URL : localhost\dashboard
16. Once the dashboard is open the create a database and the upload the database. You can find the database in the Database folder in “FYP-main”. Once all of the content are uploaded then open another tab.
17. Enter the following link in the URL “localhost\FYP-main\Manager\index.php”
18. The website will run then Login with the Manager Email and Manager Password which is “99marafay@gmail.com” “19march1999”.
19. Now the application is running.
