With the additional research on PIR devices, and
the comments left here, I have been able to
resolve the issues
that I was having with my 2 M16A’s not
picking up the motion from
Rats that are in the area.
Originally, the 2 sensors were attached to
the ceiling (pointing downward) of an outdoor
awning which sits about 6 ½ feet from the deck.
During cooler weather, this setup worked
fairly well, but as the temperature got
Warmer, the detection of these little
critters degraded or non existent.
I ended up making 2 stands about 2 feet in
height, and added the ability to control the
angle of the sensors (either up or down) and
used the help of squirrels during the
day to position both sensors to a point where
any activity from 2 primary areas that
I was concerned about, would be detected
every time.
So my problems have been resolved, thanks all
for your help and input.
Regards
