IMPORTANT
This project will most likely never be released in a way that it can be replicated by other makers. It is a repository for personal use only.
I kind of finished the project but didn't actually manufacture a dedicated PCB for it. Therefore there are no official schematics for the hardware.
Note that the
v1hardware that I did get manufactured had an unknown error in it that kept messing up the calibration of the Senseair S8 in random intervals. I never found out what the problem was.
Simple Air Quality sensor based on:
- nRF52840 (Microcontroller + Zigbee)
- Senseair S8 (CO2)
- AM2302/DHT22 (Temperature + Humidity)
- Zigbee (SmartHome Connectivity)
- DOGM132W-5 (Display)
- uGFX (UI)

Questions
How big is the AirQualitySensor PCB?
It measures 81.3 × 36.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AirQualitySensor use?
44 parts, built around the DHT22, XC6206P332MR and EA DOGM132W-5. 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 AirQualitySensor KiCad files?
From the Finomnis/AirQualitySensor repository on GitHub, at the commit this page was made from: the board is hardware/dev/AirQualitySensor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the AirQualitySensor 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).
