I replied on Monday, and was "suggested" to have been wrong, but
I'm fairly certain I've heard of methane detectors used to activate
stink maskers in restrooms.  IIRC, the surprise was that they were
able to make it cheap enough.

This was years ago, however, so the company involved may have
folded up and disappeared long ago.
