Questions
What parts does the AirSensor temp use?
85 parts, built around the CD74HC4046APWR and ESDAULC5-1BF4. 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 AirSensor temp KiCad files?
From the practichem/airSensor-temp repository on GitHub, at the commit this page was made from: the board is mg/mg.kicad_pcb and its schematic mg/mg.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AirSensor temp design in my own project?
Its repository states no licence, so its author keeps all rights: ask practichem before reusing the design.
