Make your invisible air visible
Then make it change
MONITORING
Using sensors and algorithms,
WiBreath monitors indoor air
pollution and compare it with the
outdoor one.
NOTIFICATION
WiBreath warns you if your indoor air quality is getting bad and you need to open the window to change your air.
BUILDING AWARENESS
WiBreath recognizes the specific pollution agent and gives you a relative good practice to follow.
WHAT IS THE PROJECT ABOUT?
Indoor air can become up to eight times more polluted than outdoor air.
But how to control something that you can’t see?
WiBreath is an open educational project on creating a common awareness about the indoor air pollution topic.
WiBreath is a smart system that helps you to visualise the problem and take control of your indoor air quality by using the window.
WiBreath is created to make people conscious of their environmental issues at home, in order to be able to balance it.
It builds a strict relation with the outside world, human actions and the objects around us.

HOW TO DO IT?
Wifi module
Temperature and Humidity sensor
PM sensor
VOC sensor. This component is planned but still not integrated in the actual prototype.
Window state verifier. By configuring this component into the system it would implement the scenario's precision. The WiBreath system can work also without this but its working performance will be lacking in extra verifying variable.
Here we show you all the components that you will need to build the system's hardware!
WiBreath is composed basically by two Arduino UNO boards, (a master and a slave) on which are connected equal sets of sensors. The collected data of both get compared and re-elaborated thanks to their Wi-Fi trasmitters.
At the moment the alimentation of the hardware elements is fornished by USB-cables for the inside hardware and it is already planned implement the ouside system with a solar panel power supply.
You can check the components and the Fritzing sketches down here.

SKETCH
Software components
In order to make the entire WiBreath system work completely, there are several programming steps and integrative processes that have to be matched.
The total development and synchronisation of the parts is still a work in progress.
The project is designed from the hardware modules to the interface interaction.
By prototyping we achieved the programming part in CC coding of sensors' reading, data sending codes thanks to ESP01 trasmittors, which are the first thing to configurate, on the two Arduino Uno boards. The real time data visualisation is achieved through the open source platform ThingSpeak IoT.
The configuration of the data trasmission with ESP01 has to be setted as in the following instructions.
Next would be write the MatLab code of the Algorithm, that we have already designed, to integrate the relational data aspect, thanks to the ThingSpeak's extension MatLab Data Analysis.
The Algorithm has specific behaviors to follow depending on the match of the overall collected data to the setted parameter's criteria and priorities. The inside and outside air conditions are related with the aim of evaluating the potential benefits concerning the action opening or closing windows.
Our final goal is through Algorithm in CC code with the pertinent implementations to create the data writing component. Everything synchronised directly with our interface outputs.
The sketches avaiable till this moment are on the right.

CASE
We designed two kind of cases: an indoor one and an outdoor one. The case which will stay outside is projected to guarantee a good weather resistance. The indoor case has an optimal air flow and can be positioned either hanging on a wall or leaned horizontally.
Down here you can download the laser cut drawings of the prototype's cases. For assembling them step by step, follow the attached instruction sheet and for position them correctly have a look here.

RESEARCH
Our project started from the study of our perception and use of the window and its relation with the outside world. We analyzed how our actions influence our home environment and how its possible to control the air quality through a conscious use of windows.
Therefore a research focused on the most common air pollutants, their properties, their effects and their sources has brought us to select the main parameters that will be measured by our system.
