README.mdAir quality station
V Electronics Air Quality Station design files & code, everything is open source and can be modified easily by the user. The device measures air pollution, temperature and humidity.
[!NOTE] This is a work in progress!
Specification:
Measurement range
| Air pollution | Temperature | Humidity |
|---|---|---|
| todo | Item2.1 -40°C to +80°C ±0.5°C | 0% to 99,9%RH ±3RH (at 25°C) |
- USB C power/programming (MCU fully unlocked)
- 2x16 LCD display + vertical bar LCD color display
- No battery (a powerbank can be used)
- Not waterproof
Components list
- Seeed Studio XIAO ESP32C3 link
- GRAVITY PM2.5 air quality sensor link
[!TODO] //find cheaper for example https://www.dfrobot.com/product-2526.html
- LCD Display + I2C adapter link [blocked]
[!TODO] //find suitable option
- Vertical bar vertical indicator link
- AM2320 temperature & humidity sensor link
[!NOTE] DHT12 can be used as a slightly cheaper alternative compromising accuracy and measurement range.
- On/Off switch link
- PS1240P02BT buzzer link
- 2N3904 driving transistor link
TODO
- add test points
- add drill holes to mount sensor to PCB
- add gpio outputs for extra stuff
- add led at analog output
- add made in kicad (copy from cm5 io board)
- wifi/bluetooth connectivity???

Questions
How big is the Air quality kicad files PCB?
It measures 76 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Air quality kicad files use?
15 parts, built around the PS1240P02BT. 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 Air quality kicad files KiCad files?
From the V3lectronics/air-quality-station repository on GitHub, at the commit this page was made from: the board is air-quality-kicad-files/air-quality-kicad-files.kicad_pcb and its schematic air-quality-kicad-files/air-quality-kicad-files.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Air quality kicad files design in my own project?
Its repository states no licence, so its author keeps all rights: ask V3lectronics before reusing the design.
