>you get changes on timescales of minutes to a few hours but not on timescales of days.
again, correct. That's how they're supposed to work. If the air is very slowly getting worse, MOx sensors might not catch it.
That being said, what "very slowly" means depends on the sensor. For example, for Bosch BME680 (very good with 'organics'), you can set the tracking interval between 4 and 28 days (i use 28). Sensirion SEN66 (very good with 'chemicals') can have a tracking interval of up to 1000 hours.
