Intro: Build Own Secured PHP IOT Website Free - Arduino

I feel its costly to purchase IOT from websites. So i plan to build our own IOT web page. When come to IOT the security is more essential, So i use MD5 encryption from PHP to secure the page. With the page i design we able to control lot of devices with seperate user name and password for each device. And access the data with the user name of the device.

STEP 1: Materials Required

For Programming

1) PC with web connection.

For Testing

1) Link IT one board (Or Arduino UNO with WIFI or GSM Module"

2) ESP8266 WIFI module

3) Wifi hot spot of smart phone with internet connection and WIFI hotspot.

4) Power Supply

5) Relay module

6) Potentiometers

STEP 2: Find a Suitable Web Site

Use google and Found a free Website hosting web site. Even with limited size is enough for testing. If we want to expand the project then purchase a space from them. I found 000webhost.Com is a nice web site with free database support. Database is very essential when develop a iot webpage.

The program we going to use is PHP with Mysql.

STEP 3: Free Signup and Verification

1) Sign up using your email id.

2) After verify email id in your web page.

3) Use mobile send the unique code listed in the page to the given mobile number.

4) Then your mobile number also verify.

STEP 4: Create a Website

1) When login the website.

2) Click the + sign on the web site and enter the website name and password of the website, then click create.

3) Your web site created sucessfully.

4) Use Build web site using three options given. I use upload own website. Because i develop a php web site. I give it in up coming pages.

STEP 5: Create a Domain

1) Now its time to create your domain name.

2) In the menu click my domains.

3) Then Click add domain in the screen.

4) In the domains page click Add domain.

5) In the Window click free subdomain.

6) Enter sub domain name and click save.

STEP 6: Create a Database

1) Create your PHP data base.

2) In the databases click new database.

3) Enter the database name, username and password.

4) Click create.

5) Your database created.

STEP 7: Manage Database

1) Create the tables in the database.

2) Create your tables in the php as per your requirement.

3) I given my DB here.

4) Download the local host.sql in the list.

5) Use import in the page to import the tables from file given.

STEP 8: Create Iot Pages

1) I given my php files as rar here.

2) Down load the file and change your dbusername, password, db name in config .php file and upload.

STEP 9: Upload to Website

1) Down load the pages i given and upload the pages in the upload own web site.

STEP 10: Arduino Program

1) Upload the given program in linkit one (or change it for Arduino).

2) Run the kit and found the sensor value posted on in your database.

3) By use the Sensorvalue.php with your domain name u able to see sensor value any where in the world.

4) By use the Switches.php with your domain name u able change the switch status in the kit.

Syntax for each page:

1) To see sensor value

your web domain name/Sensorvalue.php?id=User name in table&pwd=Encrypted password using MD5

2) To change switch status

your web domain name/Switchesphp?id=User name in table&pwd=Encrypted password using MD5&switch=integer in decimal to control up to 10 digital pins.

In the arduino program u want to change the addresses and wifi settings. Also add program to convert received decimal to binary value and change the digital pin status according to the decimal value.

I php I add only basic pages use the coding add plugins like graph for php from net develop pages to view the details in graph. And use image map send the switch status from php page to database to switch on and off the devices.

MD5 is not secure in any way, aswell as your whole design. It's a bad idea to send usernames and passwords in get requests. If you want something secure, it is not going to be this easy to code and set up. This is so weak and easy exploitable that I wouldn't recommend anyone building it. You're better off by using a service like blynk

Thank you very much..........Its just a try. if i can able to built any thing more secured with out using third party tools i built and share here.

Please show the arduino code for this like ESP8266

Sorry currently i have only Pi and Arduino uno in hand. I try to purchase check and reply. But i think its very simple when you develop a web page and control it from any client.

so many useful info, tnx Also Plus I read that that ssl cecurity certificates are also very important for any website. I found useful info about them on www.ssls.com. With these certificates users recognize that site is safe, and that leads to greater trust in brand online.

Hello, thanks a lot for posting this simple and excellent project.
I have a question. How and where do you create the password?

jegatheesan.soundarapandian 3 years ago

Sorry i dont develop separate page for user name and password. Go to the data base and select the security table and insert data there.

IntelliGads 3 years ago

OK, thanks for the response..
So, when we access the URL, we have to type the password also in the address?
For example, if my password is "alpha" my URL will look like below?

web domain name/Sensorvalue.php?id=User name in table&pwd=alpha

IntelliGads 3 years ago

So, you mean we have to type the password in the browser to use it?
but then the password will be viewable by anyone by looking at the browser history. Then how is it secure?

But when you transfer data you send from microcontroller so no one able to view. For report if you want you put a login screen.
