Hello! Looking for hardware for measuring indoor air quality 💨 🏠 💨 One of our housemates has allergies we're trying to track down... Hardware must detect:
- particulate matter (e.g. PM 2.5 & 10)
- volatile organic compounds (specifically wood volatiles like turpentine)
Should be as open as possible and 'affordable'. Temp. & humidity nice bonus, but not necessary. Does not need to be turn-key/can be for nerds 🤓
@douginamug I have a co-worker who loves his purpleair sensor: https://www2.purpleair.com/collections/air-quality-sensors
He has both the indoor and outdoor one.
@douginamug and it looks like they're testing adding VOC support and you can get in on the fun early: https://www.reddit.com/r/PurpleAir/comments/i11ly5/purpleair_testing_voc_sensor/
A PiSugar or UPS-Lite battery backup can easily be stacked with the Enviro+ for portability. Mine has one so the Pi doesn't go offline for hours after my cats knock the power supply out of the socket...
If needed, I can share the python scripts and the systemd service files I use for MQTT and Luftdaten. 😺
