SmartBuilding

Presentation

This application was developed in the Smart Building project realized in the Computer Engineering Project course at the University of Mons. The project consists of a building filled with sensors that send different data to an ESP32 module and then this application has to parse that data and display it in various forms for example:

• A live chart that shows real-time temperature of the house
• A live chart that show real-time humidity of the house
• Various buttons are used to notify the user about event occurring in the house

Requirements for this application

You can use this project to display your own data from your Smart Building model. All you need to do is to make sure that you create an application that writes code "sensordata.xml". We developed such a script in the "writing_Data.py" script.

After creating you repository and cloned the project you first need write the "config.ini" file. The file looks like this.

Image de config.ini

After each variable you need to adapt every pages directory relative to your www file (for wamp or xamp). In this case the default value is /html/pages/chambre.php for example, meaning the projet is in www folder inside html subfolder

After you have modified this the application should run.

Dependencies for this project.

This web application uses :

• Bootstrap
• Chart.js
• jQuery

You need these to be installed in your computer and adapt the script tags in every .php file of the project if you want to execute this application off-line.

How does the script work

To generate any of the chart or button we read the sensordata.xml, to do that we use the readXML() function this function takes no parameters and returns an object with every data parsed from the .xml file.

We then update the chart using the addData() function that we call every 1000 ms to add fresh data to the charts. addData() is called updateData() which will set the delay before calling addData() a bunch of time.
