@Robert Taylor good question, and yeah it makes a real difference to your firmware architecture depending on the answer.
The air quality sensor on the module is the kind that outputs a processed index rather than raw resistance — so you're not dealing with ADC values that you'd need to run through your own compensation math. What you get back is a usable figure you can act on directly, which is intentional since the module is designed to feed into the data network where verified, meaningful readings matter more than raw sensor output.
That said, if you're building something custom and you want finer control over how the data is interpreted, worth raising it directly with Moamen through the Dev Hub — he's been responsive about firmware-level questions and there may be more flexibility there than the default output suggests.
