I don't see how it is a repost. That submission was to an article that talks about a new model of photo-acoustic sensor from Infineon.

This submission is to an article that compares photo-acoustic sensors to NDIR sensors. Its only connection to the earlier submission is that the author of the comparison participated in the discussion of about the new Infineon sensor, updated the comparison article, and linked to it in one of their comments.

It's one of the fun things of internet forums in how you can see where someone gets nerd sniped but is able to bring back something from their trip down the rabbit hole.
