Questions
How big is the Air detector PCB?
It measures 162 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Air detector use?
132 parts, built around the ESP32-WROOM-32, PMS7003M, LM358ADR and BME280. 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 detector KiCad files?
From the shm-dmitry/air-detector repository on GitHub, at the commit this page was made from: the board is schematics/air-detector/air-detector.kicad_pcb and its schematic schematics/air-detector/air-detector.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Air detector design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
