Questions
How big is the Air quality sensor PCB?
It measures 34 × 40.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Air quality sensor use?
8 parts. 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 Air quality sensor KiCad files?
From the 3nt3/air-quality-sensor repository on GitHub, at the commit this page was made from: the board is pcb/air_quality_sensor.kicad_pcb and its schematic pcb/air_quality_sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Air quality sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask 3nt3 before reusing the design.
