You had mad the comment
so the only connection on the entire board is the sensor output into RESET
and I wanted to clarify that GND was also connected (I've helped lots of people who don't appreciate that without GND there is no reference for the signal voltages).

Yes, sorry. I see your point. I did write that. I was referring to the only "logic" connection, pushing aside the issue of actually powering the sensor, and furthermore that ground should be "common" amongst components. But you are right that such details need to be clarified.

Thanks!
