We hate cloud with a passion so there will not be a cloud integration developed by us, the most you will get is a GSM modem sending out SMS messages.
Central control unit
-doesn't actually control anything, only contains a power supply and a battery.

Questions
How big is the PIR systém Q PCB?
It measures 50 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PIR systém Q use?
44 parts, built around the CH340C, WT8266-S1, AP63203WU and P82B96D. 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 systém Q KiCad files?
From the Tomas0015/System-Q repository on GitHub, at the commit this page was made from: the board is Universal module/PIR systém Q.kicad_pcb and its schematic BATT/batt.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PIR systém Q design in my own project?
Its repository states no licence, so its author keeps all rights: ask Tomas0015 before reusing the design.
