How I use Stream Deck on Linux with open source tools

Great article.
Do I get it right that the StreamDeck is connected to the computer via USB? And that the computer then sees this as a HID, just like a special keyboard that sends "key presses" that are not in the "normal" range of a keyboard?

How to measure particulate matter with a Raspberry Pi

Thank you Stephan for that article. Every public sensor that exhibits the issues we see is a good sensor.
Please see also https://opensource.com/article/17/3/build-smog-sensor-ESP8266-microcont… for an alternative approach, where a cheaper ESP8266 is used instead of the RaspberryPI.
