Questions
How big is the Pir based night light PCB?
It measures 82 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pir based night light use?
11 parts, built around the WEMOS D1 MINI, HLK-5M05 and BC547. 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 Pir based night light KiCad files?
From the goku-g/night_light_controller repository on GitHub, at the commit this page was made from: the board is pir_based_night_light.kicad_pcb and its schematic pir_based_night_light.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pir based night light design in my own project?
Its repository states no licence, so its author keeps all rights: ask goku-g before reusing the design.
