What are the Features?
It fits into the same case and displays air quality using an RGB LED. But it could be used for something else, everything is configuable via HA
The board runs ESPHome and sends data to Home Assistant. It measures temperature, humidity, and CO₂ levels.

Questions
How big is the Cd30 Luftsensor Projekt PCB?
It measures 70.4 × 68.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cd30 Luftsensor Projekt use?
4 parts, built around the WEMOS D1 MINI, SCD30 and TB006-508-02BE. 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.
Where can I download the Cd30 Luftsensor Projekt KiCad files?
From the herrTechnok/Co2-Reader-ioT-replacement-Board repository on GitHub, at the commit this page was made from: the board is PCB -Kicad/cd30 Luftsensor Projekt .kicad_pcb and its schematic PCB -Kicad/cd30 Luftsensor Projekt .kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cd30 Luftsensor Projekt design in my own project?
Its repository states no licence, so its author keeps all rights: ask herrTechnok before reusing the design.
