Questions
How big is the DHT22 pcb PCB?
It measures 28 × 13 mm and has 2 copper layers, 1 mm thick.
What parts does the DHT22 pcb use?
5 parts, built around the DHT22. 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 DHT22 pcb KiCad files?
From the MakersAsylumIndia/M19O2 repository on GitHub, at the commit this page was made from: the board is engineering/CAD/M19O2/Humidity_Alarm/DHT22_pcb/DHT22_pcb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DHT22 pcb 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).
