Air Quality sensor

[jkotowicz1]

I wonder if anybody thought about adding air quality sensor to Sensor Watch? No idea if its feasible, but after a day in not so well ventilated office I wondered if one can measure and monitor CO2 levels from the watch.

I don't think that would be possible, since the smallest CO2 sensor currently available is probably SCD4x and that itself is 7mm high, not even mentioning the other dimensions.

What about the BME680 ? It is tiny and measures Bosh Air Quality Index and can even differentiate smells :) Only donwside would be you need ventilation which istn compatible with waterproofness and also somewhat high power consumption.. Been also thinking about measureing indoor air quality!

I don't think that one measures CO2 content in the air.

not directly but a proprietary air quality index from bosh which also measures VOCs which would be perfect for monitoring indoor air quiality...

A carbon monoxide sensor would be incredibly useful...
