Based on the title, I was expecting this article to have instructions for calibrating an air quality sensor, rather than just explaining different error types.

This post is part of a series of posts. We already wrote a few posts about sensor calibrations, e.g. how to develop a correction algorithm for temperature [1] or how to use R for making a linear regression [2].

In one of the next topics we will dive more into PM correction and the sensitivity to relative humidity.

If you want to know more about the science of air quality monitoring, we are also running webinars that you can watch on our reserach page [3].

It doesn't mention anything about calibrating

I was looking for this too, "site:airgradient.com calibrate" brings a lot of results, so it seems like they support it, but I haven't dug in yet.

What you think the purpose of determining the error of an instrument is, if not to calibrate it?
