When it senses motion, it peaks to .150ma and then settles back to .120ma in non motion state. The PIR was jumpered for Active LOW. But when jumpered for Active HIGH I read the same readings. This is real world measurements at 5v, with a fairly expensive and accurate meter that has up to 200u accuracy. I used a 10k resistor between my SX microcontroller's input pin and the output pin of the PIR to tell when the PIR was in a triggered state. The microcontroller turned on a LED when the PIR sensed motion. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=168737#m168925 Need assistance?
