I just received a new sparkfun openpir (SEN-13968) and it seems like its not working. The Green LED stays on full time no flashing. Am I doing anything wrong? I am using a regulated 5V supply also tried 3.3V its still the same. The xLED jumper is obviosly connected to GND with solder. Also... when the 'OUT' pin is on high (not the Analogue out) what is the voltage expected there?

Have you tried adjusting the trim-pots by chance? I think having either or both set t to maximum or minimum may cause strange effects.

I believe the voltage on the pin should output what you are supplying the device. If using a 5v supply, the output pin should be 5v.
