Parallax PIR External Sensor
The website shows that my external motion sensor is always open. My understanding is that this sensor should work as it's output is digital. The sensor works and is connected. Am I ahead of your website development or do I have a problem.

TO CIRCUIT is where you put the PIR. Connect: GND(Breakout) to GND(PIR). 10K(+2-30V) end to OUT(PIR). & 3.3V(Breakout) to VCC(PIR), IN & GND in circuit above are on Twine Breakout.
