Hello! I am from Ukraine. It's really interesting not only for me but my students also. How I can connect to this project. Thanks!

Hi @GreenFrogg! Impressive work! We are now testing the potentiometers of the Shinyei PPD42 here in barcelona using two sensors on the same plastic box to be sure of the variable resistance value needed for the sensor to mesure correctly. Do you think is possible for you to measure the potentiometer values of any of your stations using a multimeter? You can help us on this research note here ;) https://publiclab.org/notes/imvec/12-12-2016/dustduino-potentiometer-testing

@xose: My sensor is already enclosured. But there are still sensors to be installed. I will put the question on the project forum (in dutch language) https://samenmetenaanluchtkwaliteit.nl/projecten

Thanks a lot @GreenFrogg!! That would be great!

Done! See the picture

Woooow!!!!! Thanks a lot!!!

Compilation of the firework PM peak @ the 76 sensors. The Yellow points are the overall average and the bleu dots the local values

East & middle of the Netherlands: Deventer, Zwolle, Wageningen, Groningen, Nijmegen, Arnhem en omgeving: Results on the same scale

Oh, this is very neat. Thanks!

History of each sensor point now available for evaluation. It's downloadeble as an Exel file. Just click on the the sensor and choose: "verrijkte dataset". http://meetnetdata.rivm.nl/vuurwerk/ and there is also an English page: https://www.samenmetenaanluchtkwaliteit.nl/international and https://www.samenmetenaanluchtkwaliteit.nl/sensor-meeting-february-13th-2017 One can also look at the twitter account: @samen meten.

Fantastic map!

Now the new measurements site for new years eve 2017/2018: http://lkvis.rivm.nl/dashboard/db/vuurwerk?orgId=1 for more info see: https://www.samenmetenaanluchtkwaliteit.nl/international

It looks like this:

Oh wow! These are great graphs -- maybe post a new note with them? Would you be interested in doing a short blog post about it? Happy new year!

This is one hour after midnight:

@ Warren, I will try to make a blog. Have to make time :-). There are a lot of differences with the measurements last year. Several different (and mostly new) sensors and the (successful) use of LoRaWAN beside WiFi, measuring 2,5 and 10 and the graphics in ug. There is also information in the English language here: https://www.samenmetenaanluchtkwaliteit.nl/international

Fascinating!
