 My trigger range has dropped considerably,im going to assume that low Batt will do this,so im going to change it out today.
 Was wondering if the temperature drop will cause this? or as im thinking a combination of both will affect range of sensor? Right now in Missouri its not really cold,maybe 50's during the night.

Colder weather should extend the range of the PIR sensor.  I won't pretend to know the range of the extension.  Just like the HOT weather reduces the range colder weather increases the difference between the surrounding temperatures and the animal.  My guess would be the battery is weak.

Hi Passthru,
Another possibility is that during use the unit has been knocked around a bit.  This can change the placement of the sensor element behind the Fresnel lens.  Even a change of 1/16 inch can cause a dramatic shift in sensitivity.

 I cut the housing it came in to the shape of the board so that the fresnel lens was the only thing sticking out and still have the housing on the inside of the box holding the IC board in its original grooves.
 Notice in the pics i posted how its still there.I just didnt use any glue opting for the foam inside to hold it forward.(i have foam to remove from box to get to camera not shown in pics)
