Airrohr V2 (luftdaten.info)

The parts belong to the "Feinstaub Sensor Projekt" -> http://luftdaten.info/feinstaubsensor-bauen/ and employ a box instead of 75mm tubes. I possess a 3-D Printer - that's why I print my box. Boxes house a SDS011 and a NodeMcu (+DHT22). Version 1 is designed for a NodeMCU with CH340 chip. Version 2 is tailored for a NodeMCU with CP210 chip. I utilized 10 mm nylon spacers to mount the SDS011, as well as additional 6mm spacers to secure the cover plate, visible in the picture. A DHT22 was placed on top of the lid; you may open the prepared hole. An "Aufhaenger" is fixed with Tesa "Powerstrips," according to my specific needs.
