Dear community,
My name is Matt and I used to be very active with Code for Germany and on air quality measurement (both in the community and then also for a long time professionally). I was given a long time ago 10 sets for particulate matter measurement from the project leaders in Stuttgart, the idea being to stock them up after workshops. The last workshop I hosted was just as the corona pandemic was getting started, we only used three sets. So I have 7 sets here, and would also top the box up with more sensors/parts for a project that is relevant at the moment (particulate matter, noise, radioactivity, whatever) so that we end up in a situation where I haven’t profited from the money people gave me for the sets last time.
If anyone needs some sets, please let me know - they should be used for a charitable purpose (i.e. not just sold on again), and I’d only want some money for the postage. I also travel a bit, meeting up anywhere between Munich and Frankfurt (via Ulm/Stuttgart/Mannheim/Nürnberg/Würzburg) is also possible.
