RIoTboard and Xtrinsic Sensor Webserver Temperature Logging Demo for IoT Application

This is a summary of both Tushar's RIoTboard webserver blog and my single webpage project that extends Tushar's webpage project. For more information and a detailed walk through of both projects please follow the links above.

Okay so the link to the SD card image of the finished project is at the bottom of the page, but before I just hand it over I am going to tell you roughly everything that has been done to get this demo working. This will be a very brief overview of both projects literally just highlighting the changes. I will not be going into any specific details.

Getting Started with RIoTboard:

Okay so the first thing we need to do is to get the Ubuntu image that element14 has provided onto the board.

We then need to install the packages needed for the web server and for the code for the Xtrinsic board

apache2
mysql-server
mysql-client
php5
php5-mysql
libapache2-mod-php5
php5-cli
php5-gd
libmysqlclient-dev

These can all be very easily installed using the "apt-get install " command as they are all in the package repository.

The webserver now runs and can be accessed by entering the boards I.P. address in a web browser (i.p can be found by typing "ifconfig" into the terminal). But this is the default apache page, we need to change that.

Getting Started with Xtrinsic Sensor Board:

So to get the Xtrinsic sensor up and running there is quite a bit of C code which we then need to compile and run ("xtrinsic_temp.c" and "xtrinsic_mysql.c"). We used gcc compiler for everything.

We also need to set up the SQL server for our sensor data by adding a new database and table.

More C code ("current_temp.c") is then run to populate the SQL table with some data from the Xtrinsic sensor board.

This is the c code that needs to be run every time we boot the RIoT board in order to keep live data coming from the xtrinsic sensor board

The Xtrinsic sensor is now running.

Getting the Web Pages Running:

Now we need to get the basic web pages up and running, this includes 3 php pages to display "current temperature", "temperature graph", and "control the LED". This is just a matter of copying them into the "/var/www" folder.

Next we need to link them into one webpage.

To do this we are going to use an HTML page which has "iframes" showing the php pages in a table layout to make it a bit more attractive.

This HTML page will be called "index.html" so it is auto loaded by apache whenever someone accesses the server, and it will display all the php pages through "iframes".

Fine Tuning the Web Pages:

Now we are going to fine tune the web pages to give them a more professional look and to make them more user friendly.

To do this I have changed all of the php files ever so slightly, this gives them better control and integration into the HTML page.

I have removed all the text from the php files, got the led control file to load the appropriate bulb picture depending on whether the LED is on or off, got the current temp php file to display a °C sign, and got the graph to delete any data in the sql database that is older than 15 mins, this speeds load time and reduces excessive data.

Add Some Graphics:

Every web page needs some pictures and this is no different, we are going to add a RIoTboard logo and an element14 logo at the top of the page, and a background behind everything.

We are also going to add two LED pictures so the "led_blink.php" file can load the appropriate one; depending on if the led is ON or OFF.

Running Everything on Boot:

We now need to get everything to run automatically on boot so that we can run the server headless every time.

To do this we are going to write a script that will run the necessary C code ("current_temp.c") at boot up and set the permission of the www folder (to read and execute only, and the bulb images and the led control file to full access) so that they are set correctly and so we wont need to do anything.

The custom boot script is in the "/etc/init.d" folder, then it is made executable, then we tell linux to include the script in its boot process at the end using the command "sudo update-rc.d script_name.sh defaults 99".

If you are going to use the image below you will need to enable the start.sh script before you use it using the command:

sudo update-rc.d script_name.sh defaults 99

In the script we run the C code and set the permissions for all the images and the led control file to full access, and everything else in the "www" folder to read and execute access.

Reboot and you're off:

The header says it all really.

To download the complete SD card image click the button below, extract the image file, flash onto an SD card, and boot your board, you can download it HERE

You will need to enable the start.sh script before the web server will work. To do this use the command "sudo update-rc.d script_name.sh defaults 99". Then reboot the board.

The static I.P of RIoTboard for my image is 10.11.128.116 . Just type that into your web browser once you have your board up and running and connected to the internet and it should load the web server.

THE DOWNLOAD BELOW CONTAINS THE FILES USED FOR THE SERVER, THESE ARE NOT NEEDED IF YOU ARE USING THE IMAGE ABOVE AS THEY ARE ALREADY INCLUDED.

THE DOWNLOAD BELOW IS IN CASE YOU WANT TO LOOK AT THE FILES USED WITHOUT DOWNLOADING THE IMAGE AND FLASHING AN SD CARD.

RIoT Board and Xtrinsic webserver

Former Member — Mon, 23 Mar 2015 13:24:45 GMT

Current Revision posted to Documents by Former Member on 3/23/2015 1:24:45 PM

I'm going to guide you through the process of making Tushar's Webserver a single aesthetically pleasing html page that works every time straight from boot.

Like This...

Preamble

So before we start I would like to say thanks to Tushar for doing all the complicated C code and php for this project, You can see how to set that up in his 4 part blog, here.

In this blog we are going to bring the web server sections all together into one neat webpage and get everything to start properly on boot, so it runs completely headless every time you boot it up, no issues.

For this project you will need a working version of Tushar's RIoT Board and Xtrinsic webserver, if you do not have it you can go to Tushar's blog and follow that.

Note: All of the files I have used here are in the .zip at the bottom. Simply unzip it and copy the www folder to /var and the start.sh script to /etc/init.d then run the necassary linux code (about 15 lines up) for the start script and you are done.

If you want to make it yourself, or simply want to know the changes I have made here they are.

So you should start with something looking like this.

and a few webpages that look fairly basic.

But we want them to look like this

So there are two parts to this. Firstly getting the html page up and running to get the single webpage that does everything, and secondly to get it to run automatically on boot.

The All-in-One HTML page

Being the easiest and most straightforward of the two, we'll start with this. Basically we will have an HTML page with a frame for each php page and a few extra things to make it look good.

The design for the page is a basic 2x4 table with the logos and the description going across both columns and the graph going across across two rows, and a css script to make it more eye catching and exciting. If you don't want to write your own html page I have included my script below, if you do want to write your own script below I strongly recommend using a table for the layout of your page and use iframes to display the php pages, this will allow you to write you page far faster and also make it easier to find the relevant piece of code if something goes wrong.

<HTML class='main'>
<body>
<title>RIoTboard Demo</title>
  <link rel="stylesheet" type="text/css" href="css.css">
  <table class="main">
  <tr class="logo">

  </tr>
  <tr class="header">
  <td colspan=2>
  <h1>RIoTboard demo with Xtrinsic sensor kit</h1>

  <br><br>
  </td>
  </tr>
  <tr class="main1">
  <td class="main11">
  <h2>Current Temperature</h2>

  <iframe src="led_blink.php"class="led_control" frameborder=0></iframe>
  </td>
  </tr>
  <tr class="inf">
  </tr>
  </table>
</body>
</HTML>

and the css script which is named css.css

html.main {
  background-image:url("/images/background.png");
  background-size:100% 100%;
  font-family:Arial, Helvetica, sans-serif;
  }
table.main{
  border:0;
  width:80%;
  margin-left:auto;
  margin-right:auto;
  }
td{
  border:1px solid black;
  }
img.riotlogo{
  width:40%;
  float:left;
  }
img.e14logo{
  width:40%;
  float:right;
  }
td.main11{
  width:20%;
  height:75px;
  }
td[class*='main']{
  vertical-align:top;
  }
iframe.currenttemp{
  position: relative;
  height:50px;
  top:-30px;
  right:-5px;
  }
iframe.linegraph{
  width:98%;
  height:85%;
  }
div.ledindicator{
  background-color:#000000;
  position:absolute;
  text-decoration:overline;
  right:100px;
  width:100px;
  }
img.therm{
  z-index:-1;
  height:40px;
  }
span.temp{
  font-family:Arial, Helvetica, sans-serif;
  display:block;
  }

so that that's pretty much it, I slightly edited the php pages as well.

LED Control

on.php and off.php (which run when you press the on or off button for the LED) now change the led.png image (which is the light bulb) so that the it shows whether the LED is on/off. Also I changed led_blink.php, which displays the buttons and runs the on and off scripts, so that it displays the led.png image next to the buttons.

Current temp

The current_temp.php file I changed so that it showed the °C symbol and the font is the same as the rest of the page by reference css.css

Line Graph

Line_graph.php has been changed a fair bit. I got rid of the title and the box to make it more simple and cleaner. I put a SQL query in that deletes all data that is older than 15 mins, so that the Pchart library doesn't get overwhelmed by data (I left it running when I went to lunch, came back refreshed and the php just didn't load, took me ages to work out that the pchart library has a 30s time-out for drawing the graph), you can change the kill time for data but bear in mind that data is taken every second so 15 mins of data is still 900 points of data being plotted. As you can see I have had a little problem with the X-Axis of the graph, the pchart library prints the label from every data point, and I haven't yet found a way to make it tell that the label is a time and then label the axis neatly without overlaps.

The PHP SQL query I used was mysql_query( "delete from sensordata where time<date_add(now(),interval -15 minute)");

Images

I have added a few images all in a folder called images, keeps it neat. the first one is the background, I have set it to be used in the main html page and to be stretched so that the borders are 10% of the page each. I have also added a picture of the logos that are at the top of the page. There is also therm.png which is the thermometer for the current temperature. Finally there is BI, and led.png. on.png and off.png are fixed images of the bulb on and the bulb off. Everytime the on or off button is pressed then the necessary image of on or off.png is copied into led.png to be displayed. Probably not the neatest or most efficient way to do it, but it's easy and simple.

Start the server properly

One of the main problems I had when I first did Tushar's server was that a lot of the permissions reset every boot meaning that you had to enter a few lines of code every time you rebooted. So that had to change. My preferred method for stuff like this is to make a custom script that runs on boot and in it are the commands that I need. To do this you need to make a script in start.sh I always call mine start.sh so it is easy to find, and in it I put all the chmod commands I needed.

make the script

sudo vi /etc/init.d/start.sh

In the script type

#!/bin/bash
sudo chmod -R 755 /var/www/
sudo chmod 777 /var/www/images/led.png
sudo chmod 777 /sys/class/leds/user_led/brightness

this allows everything in the www folder to be read and executed by Apache but not written, exactly what we need.

It also then allows Apache to change led.png so that the led indicator works properly.

Finally and most importantly it allows Apache to change the brightness file for the user LED allowing them to run it on and off. THIS NEEDS TO HAPPEN EVERY BOOT ELSE IT DOES RESET.

The chmod commands other than the brightness one simply ensure that the settings are correct on boot.

one of the other problems I was having was getting the c code to run on boot, if it doesn't then the Xtrinsic temperature isn't read and nothing is updated. I had a problem compiling the c code I edited to make it run without asking whether you wanted to debug or not so the command here just passes the value 0 for the user input, this disables debugging. "yes 0 | sudo /var/www/xtrinsic_current_temp &"

I also put in a command that reset led.png back to the off image every boot to be accurate to the led.

the final start.sh script should look like this

#!/bin/bash
sudo chmod -R 755 /var/www/
sudo chmod 777 /var/www/images/led.png
sudo chmod 777 /sys/class/leds/user_led/brightness
sudo cp /var/www/images/off.png /var/www/images/led.png
yes 0 | sudo /var/www/xtrinsic_current_temp &

save the file with ESC+SHIFT+: then type wq enter

so now we need to tell the board to run our script on boot.This is very simple, and only needs two lines of code.

Sudo schmod +x /etc/init.d/start.sh

makes the script executable

and then

sudo update-rc.d start.sh defaults 99

tells the board to run the script on boot.

The second line will throw up a couple of errors as it isn't actually headed correctly, but it will still run just as we need it to. If you want to header it correctly you can find the info in /etc/init.d/README

That should be everything. Just reboot the board and load up your internet browser on your PC and load your boards I.P. address. You should now have a fully working single html page. Test out the features by heating the xtrinsic with you hands or clicking the led buttons. The graph will refresh every time you load your page.

If I manage to get the graph to auto reload every minute or get the graph's x-axis looking ok then I will update the blog.

Or you can download the Full image, with everything pre configured, by clicking the button below.

Any problems? Just ask.

Any suggestions? Please please please comment and share.
