 I heard Olaf Peters from Isseline saying that we can do things that they cannot do and vice-versa of course and I think Leuvenair is such a project because the question was raised how many stations are there in Brussels. Well in Leuven there are no official stations so the the the nearest official stations official station of AMM is in Arshot which is 20 kilometers away. So this is one of the motivation to start this motivation to start this project and it is very very it has a lot of resemblance with the Influencer project here in Brussels. This was the map of sensors of low-cost sensors in Leuven one month ago and now one month further there are now almost 70 of these in Leuven so we had a very big big project together with with two partners to to realize such a high density high resolution network and I will explain the process that we did to achieve this. So what is Leuvenair as I already told you we have the same objectives as Influencers so measure find us their particular matter in in a high resolution and driven by citizens so it's a community driven initiative for air quality measurements but it's also about raising awareness so it's not only about using citizens as as a crowd sourcing sent the crowd sourcing source in a pure crowd sourcing project you just take the citizens as a kind of sensor drones this is not what we want to do in this project we also want to raise awareness and to involve citizens with the all the problems in air pollution. We also share some common developments with Influencers and there are some some very nice platforms to share common developments like we communicate through a dedicated slack space and the code is shared on youtube. Histories though a bit different and here I show the timeline of Leuvenair so we started with a website in November 2017 and I contacted some well I contacted Stratovolve which is a which is an existing citizen platform in Leuven working around mobility and they were so enthused about the project that they immediately decided to buy 100 sensor kits to install in Leuven. We had some media attention for example there was an item on the vet news in December and I had an interview with Radio Inn so the news was spread quite easily and we we searched for 100 citizens in Leuven to volunteers to hang the sensors and we organized two big workshops on the 30th of January and the 7th of February to actually make the sensors by the citizens. So first there was a presentation from Frans Ferenc from Inserline kind of scientific introduction and then the second part of the evening was really devoted to making the sensors what some of you are going to do this afternoon and then out of Leuvenair the Civic Lab was also started well we are going to start next Wednesday we will have the first Civic Lab and also there the the objectives are the same as Civic Lab Brussels. So here I mentioned the two well the most important partners that we are collaborating with so it's Stratovolve I already mentioned this so they gave in fact the budget to buy these 100 kits and their budget came from the province so the province of Lamze Brabant they gave a budget of 75 000 euros to to organize projects around climate and we got a small part of this budget to buy these sensors. On the other hand we have also quite some support from the city of Leuven for example we could use the room for the workshops for free and also the room for the Civic Labs will be free so they are also supporting us in another way but I will discuss that later so these are some impressions of the workshop the pictures are some of the pictures are rotated sorry for that so it was I think it was a very nice success and it was also a nice way of communicating direct communication with the citizens about air quality you see that all kinds of people were there I think there was not really a gender equality there were very few female participants so that's maybe a point we can work on so what's next so I will present four plans or four possible routes that I see to to to develop so first as I already told you we have the Civic Labs we will convene every two weeks on Wednesday evening and the objective is really to work also with data so we would like really to analyze the data and to see where are possible hotspots in Leuven of of particulate matter on the other hand we also want to do some technical development for example first place to to improve the website but also we would like to do some hardware development for example the KU Leuven University of Leuven they have an unknown Lora Lora network and we could use that for free to test the the Lora solution that was developed by Influencer also we need some people that are better than us in in communicating social media we are doing it now ad hoc and we don't know lots about citizen engagement and we would like to recruit some experts also in this matter another thing and personally I think this is a very interesting one we are starting also collaboration with the ad hoc section of the architecture department in KU Leuven and what they are actually making for the moment it's still in progress they are making low cost screens like this so it's e ink screens that you can find for example also in the supermarket to display prices so their plan is to develop kind of screens that you can put as a citizen in your street and to display all kinds of information and a key ish a key feature is also that there is communication about this information so you have there these buttons with these smileys and you can push the button if you like or dislike this information so and they would like to show the data from Leuven ad on the screen so the the idea is really to display the information but also to interact with the citizens on this information so just starting it's not yet rolled out but I think this is a very very nice development the city of Leuven also supports us in another way so citizens can now order buy the the the city a low cost sensor that they can that they can connect them to to Leuven ad so they will give the they will they will buy the material the stuff to make it and then the citizen has to has to install it at his or her home so there are of course some requirements there and then the courier isn't is already mentioned a few times here and we have now the budget to to buy for the 100 participants of Stratovo Leuven so the 100 sensors in Leuven we have now also the budget to buy for them these passive samplers for NOx or NO2 and in the in the project they will have priority in the selection of measuring points because then we have really at the same spot a particular matter observation and NO2 observation so that's a very nice collaboration with mainly it was by done by Ircellina so thanks for that that we have now also a connection with this project so I want to to end with these slides because I think we have now discussed whole morning about air pollution and air quality and I think it's a serious matter and it's it should be studied in a serious way but I think measuring is also fun and that was also part of my motivation because I really like this to to to make my own sensor and to install it in at my home and to really know what is happening in in your place it's it's really a very nice thing and so these are the things that you will need to to make the sensor to the the one that we are implementing so the SDS 011 and I think it's amazing that you can make from these ordinary things a spot where you really derive information about the air quality of your of your place so these are sorry the pictures are rotated again but these are some some examples from Germany so where they have also a contest in making the most beautiful one and and then of course it's it's all about these graphs so you can see whether your air quality at your place is better or worse than the official measurement of course taken into account all the the the issues that you have with low cost sensors that's also very important that you communicate about that and for this is an example of my sensor where I could spot some neighbors having an outdoor party at my backyard and they were using fire pits so producing a lot of particulate matter so this is a nice example and this one is also a nice example so it was not it's not my own sensor but with this sensor we could we could detect a wood no and a house fire in the in the direct vicinity of our sensor so that's that's maybe pretty smart but it's nice to show and it's it illustrates I think also the the nice things that you can do with your sensor it's not only about the serious signs for air pollution but it's also just fun to make it and to hang it at your home thank you
