This is air quality code using a PM2.5 sensor and an SGP30 gas sensor. It can be used as an indoor or outdoor sensor, though I intend to put it in a Stevenson screen and put it outside.
- Raspberry Pi 4 4GB (way overkill)
- ICE Tower low profile active cooling system
- Pimoroni mini black hat hack3r GPIO extension
- Sparkfun qwiik hat
- Adafruit PMSA0031 STEMMA QT PM2.5 sensor
- Adafruit SGP30 STEMMA QT gas sensor
