Questions
How big is the Humidity monitor PCB?
It measures 31.5 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Humidity monitor use?
2 parts, built around the SC0918. 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 Humidity monitor KiCad files?
From the tomaisthorpe/embedded repository on GitHub, at the commit this page was made from: the board is humidity-monitor/hardware/board/Board/Board.kicad_pcb and its schematic humidity-monitor/hardware/board/Board/Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Humidity monitor design in my own project?
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).
