Re: Occupation sensor that works with people sitting still?

[Charles Sullivan <cwsulliv@xxxxxxxxxxxx>]

I don't know if anything ever came of the project, but remember
reading during the Vietnam war that the US Army was looking at
a sensor for detecting the presence of human activity along
jungle trails using bedbugs.

Bedbugs are apparently highly attuned to the smell of humans
versus other animals and display a measurable degree of
increased agitation when humans are nearby.

Of course you'd have to provide them with a real meal once
in a while to keep them alive and maintain their interest.  :-)
