    I ordered three of these sensors through a supplier in the UK (Hobby-Electronics) and all three are wired different from the images shown on both the sparkfun as on the hobby-electronics website. My three sensors have the red and black wire reversed so the wiring then becomes even stranger than before: - Red: Signal, alert. - Brown: Ground. - Black: Vin (9 volt battery).

    I first tried wiring the sensor as shown on the datasheet and that didn’t give a good signal. The output signal became around 2V and remained constant around that value.

    When I reversed the wiring (black to +9V, red as signal) the output signal was as it is supposed to be.

No public wish lists :(
