I have a PIR (passive infrared) sensor on a motion detector circuit

build, or something to buy (preferred) that I can do this with? I want
to be able to "see" (figuratively speaking that is), the cone, how far
out it goes, etc, with this circuit. Any help would be greatly
appreciated!

You can also get specification sheets on the web from many manufacturers,
which will probably include a fairly accurate map.

Already got those, but, of course, they are not representative of what
I am seeing with my application. I thought if there were a quick way
to check this out, I could find out if there were any issues.
