If yes, then put something about feet from the sensor - the ceiling makes a nice target if you're working on a table. The voltage at tha AN pin, again with the black DMM lead on the GND pin, should be about 0.6 volts - more precisely, it should be 0.01 volt per inch. 60" = 0.6 V

If all that is fine, the sensor is working properly.

Thanks for the help. I'll try this tomorrow.

What should I do if the sensor still remains at the constant 4.56 volts or so?
