Where are the script source? I'd love to look at them and see if they can improve the Purpleair one I released.

Thanks, that is the most important one. All city wide nets use those scripts also to build their own versions. But the arduino code remains the same.
The sensor can upload to the two main sites, API Luftdaten.info for the sensor database and API Madavi.de for the graphs.
Then there are pre-set uploads to OpenSenseMap and api.luftdaten.info, for which you have to set your own credentials.
And most important, every 2 1/2 minute measurement (pm2.5/pm10/temp/hum) can be uploaded to your own website also. Or to a local/city site. The website script which receives the data, can re-upload the data to another site a.s.o. The uploaded JSON with the sensor measurements can be saved as is, and / or converted to CSV and / or saved in a 24/hr csv. Probably someone also made a version to store the data in a DB.
For the users here in Leuven, one big plus (beside the price) is the open-source. Every line of the code can be checked. Also automatic firmware updates can be switched off.
I attach a copy of the config page of the sensor which you address locally by IP and has its own webserver with multiple pages.

Hi, can you supply link for the Hardware?
Is it this one: https://luftdaten.info/feinstaubsensor-bauen/ ?

https://luftdaten.info/en/construction-manual/ is the almost all english one. Only the shopping list part is still untranslated. Below that it is english.

These were out of stock when I read this post. I put myself on the "back in-stock" notification. I received the notification Monday, and ordered one that day. At the time, they had 73 in stock. I received shipping notification Tuesday, and received the Plantower device yesterday.
In checking the Adafruit site this morning, they are already out of stock again.
Just hooked it up this morning and it works well with the demo script.

If you wanted to make a sh**-ton of these things, you could probably do it cheaper.
Here's the article:
