Is anyone familiar with the motion sensors on a Police 911 ? I pulled the non-working corner
sensor boards out and found corrosion on the traces right below the (piezo?) sensor. The
corrosion was consistent with battery leakage. Since the damage was in the same spot
on both boards I presume the sensor itself had some kind of fluid that leaked.
Does anyone know what there sensors are ? They look like small piezo speakers
or ultrasonic emitters. I can't find any info at all on these boards.
Thanks,
John
