UAS move a lot of air - I can't imagine this would be practical. At the very least, you'd need to put the sensor on a boom long enough to make it unwieldy.

Many of the described robots in the mujoco_menagerie gallery could probably do the job: https://github.com/google-deepmind/mujoco_menagerie

The sensor recovery time limits the sampling time. A 28 second sensor recovery time with SnO2-Gr (graphene oxide) would be more useful for sampling larger volumes than minutes with just SnO2 FWIU; https://news.ycombinator.com/context?id=46521695
