Do anyone have any experience using IR motion senosrs on those outdoor
security lights.  In my area sometimes they would go on sale for about
$10.00.  Has anyone tried interfacing them to computers for robotic 
applications?  They have a range of up to 100ft and field of vision of 
110 degrees.  That is much better then the range that I'm getting with
ultrasound and IR LEDs.  Any input will be appreciated, thanks in
advance.

Dave
