Air pollution is a global issue in today's society, it is the cause for numerous illness and causes disconfort. This is why we have tried to build a system that could track both your gps location and the air pollution at that exact spot, to then be able to collect and add up the data onto an efficient and easy to understand format.

Step 2: Choosing Our Components

SECOND LESSON:

Step 3: Getting Our Components

The objective of the day was to get our components and try to

start something with them.

All the stuff we bought has been taken in picture and joined to this post.

During the session, we tried to connect the air sensor to the Arduino Uno Card and we used a code we found on this Instructable user profile : https://www.instructables.com/id/How-to-use-MQ2-G...

*The MQ135: Ce capteur est sensible au CO2, à l’alcool, au Benzène, à l’oxyde d’azote (NOx) et à l’ammoniac (NH3).

*MQ7: CO senor

*MQ2:

*Le MQ-2 est un capteur qui permet de détecteur du gaz ou de fumée

Step 4: Connecting the GPS Sensor

The mission of the day was to connect the gps sensor to the

arduino card and be able to read the geolocalisation data.

To do that, we had to solder the wire to the gps sensor, and then connect it to the card. We didn't really succeed in making the code, so we will continue it next session.

Step 5: Experimentations and Wiring

The mission of the day was to wire the different sensors to the

Arduino Uno card and then try some experimentation to see if the sensors are working.

*First step : put the MQ-2 sensor in a box full of smocke

The code we used is on the image, and the experiment on the video.

By doing it, we saw on the arduino monitor a real increase of the curve, which allows us to think that the sensor is working.

*Second Step : put the MQ-135 sensor in a box with alcohol in it

The code we used is on the image too, but we didn't take a picture of the experiment because it's quiet the same as the first one.

Thanks to the experiment, we saw that the sensor worked too.

*Third Step : make the MQ-7 sensor work

The code is on the image too. We didn't have access to a big source of Carbone monoxyde so we tried the sensor with the air of the room.

The more important thing in these three steps was to make sure we were able to read the data from the sensor thanks to the codes.

Fourth Step : Bring the GPS sensor to work and connect the three other sensor

Landry succeeded to make the GPS work with the code he wrote. You can find the codes on the image.

Step 6: Final Codes

We combined our sensors codes with our gps code.

The only issue we had was the altitude which won't work. We found out that altitude needed a lot more time for the satelite to calibrate our position.

However, that wont be a real problem as we have chossen not to use alltitude and consider all the data gathering to be done at ground level.

Step 7: Translate Collected Data to a Visual Reprensation

Now that our code works properly we have to make use of the data we collect. We have a decided to use some kind of map to represent the consentration that the sensors are picking up.

The First step was to convert the gps coordonnates into a physical reprentation on a map. After finding the right tools and understanding how to use them it was done.

We used e-Maps on excel to make our map using the data we gathered.

The project is now officialy finished, don't hesitate to contact us if you need any advice or if you have any question or tips for us.

Sincerly, the CEL team.
