Some ideas for further #EMFCamp #Oxygon #CO2 / #AirQuality monitoring app development, per https://codeberg.org/martin_hamilton/tildagon-oxygon:

Feel free to have a go at any of these, and send a PR...

• Add support for other common CO2 sensors, e.g. SCD-40 (also high accuracy but slightly cheaper), SGP-30 (eCO2 but cheaper again) and... ?

• Add support for other air quality metrics e.g. SGP-30 also monitors VOCs.

• Add some other functions to the library - e.g. calibration. This is just a
  matter of sending the appropriate command sequence to the sensor, copying the code from the existing functions.

• Improve presentation of results - e.g. options for font size, colour scheme, use of LEDs to signal air quality, graph CO2 / temperature / humidity levels.

• Use buttons to cycle through options, and save the selected option so that it becomes the default when the app is next started.

• Add support for running the app as a "background", with an at-a-glance indicator of CO2 levels.

• Add logging capability, saving readings to the Tildagon's internal storage.

• Add network logging capability, via wifi or perhaps Gadgetbridge.

• Add network time support if required for logging / stats processing?

• Add GPS support to logging, so we can track (map?) CO2 levels as we move around.

• Design a hexpansion PCB which includes the SCD41 sensor, a cheaper sensor that gives "good enough" readings (SCD40, SGP30), or that mates with the common CO2 sensor boards?

For the folk who were interested in #Tildagon #CO2 monitoring #Hexpansion, here' s a very hacky first stab at #Oxygon, a Tildagon app to talk to the #SCD41 sensor for high accuracy CO2 monitoring: https://codeberg.org/martin_hamilton/tildagon-oxygon

This is in the Tildagon app store as https://apps.badge.emfcamp.org/apps/00441330/, but requires a breakout hexpansion as per the README.

NB still need to add calibration mode, but it's a start! Some further ideas in the README - PRs welcome :blobthanks:

I quite like the idea of logging CO2 by GPS (or wifi?) geolocation, perhaps over the network, and displayed on a/the #EMFCamp map. Crowdsourced #Datenzwerg could happen :gnomeHey:

Now to hit the #Kicad and see if I can figure out how to design an all-in-one PCB. Or perhaps a PCB that can easily be mated with the common CO2 sensor boards, the same way the Tildagon screen attaches to the front plate?
