Hi all, I am trying to connect a Parallax PIR motion sensor to a mini-usb cable. The PIR sensor has three pins: GND (negative), VCC (positive) and OUT. The USB cable has four connections: GND, VCC and the DATA (+ and -). I am able to power up the sensor and see a voltage spike when motion is detected. However, I am unable to do anything with the OUT pin. I tried to connect the DATA (-) and then the DATA (+), but my system does not see anything using SnoopyPro. When I figure this out, I would like the voltage from the OUT pin to trigger a system response; perhaps a custom program to monitor this. Any ideas? Thanks in advance.
