feinstaubnode is a citizen science project measuring air quality (PM2.5/PM10) and temperature/humidity across Germany.
Feinstaubnode is an open-source printed circuit board by kiu, from the kiu/feinstaubnode repository on GitHub, published under the MIT licence. It is a 2-layer board of 89 × 73 mm with 8 parts on 6 nets, routed with 49 tracks and 0 vias.
It is built around the DHT22. Its parts include 2 ICs and 1 connector. It belongs with the ESP8266 boards of this library.
First try at using KiCAD.

The 3 most common of 8 parts.
It measures 89 × 73 mm and has 2 copper layers, 1.6 mm thick.
8 parts, built around the DHT22. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the kiu/feinstaubnode repository on GitHub, at the commit this page was made from: the board is pcb/feinstaubnode.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
