 declaimed the following:


> The best I can make from your description is that you are on pin 29
>(GPIO5) and pin 39 (GND). Note that your code (from the first post) wants
>GPIO6 (pin 31)! https://gpiozero.readthedocs.io/en/stable/recipes.html

 And just a follow-up comment. Since the sensor connection is GPIO and
GND, the odds are good that it is relying on a pull-UP (to 3.3V) resistor,
and the sensor closes/shorts to ground when active.
