Welcome to CNC
I thank you for the complimentWith 54 years in electronics I always hope I can help.
The resulting voltage will vary some by the tolerance of the resistors.Remember the resistor tolerance is + and -.Based on 5% resistors the output range calculates to anywhere between 4.51-5.09 volts to the Z input. All of which the micro will see as a HIGH.
i looked up your partyou still need the 2 resistor voltage divider.or you will burn the microprocessorthis is not floating, there is a n internal pullup resistor. you are seeing the pullup voltage when open. if you want a better idea of why lookup Thevenin Theorem it best explains it
A trick;DON'T ATTACH IT TO THE HOUSE. leave a few inches and make it free standing.when the assessors do updates they will try to make the deck added value and increase the realastate tax.Almost all states in their legal jargon asses "attached".I beat the assessment on a challenge and got the tax removed.
Yes the K is the Greek kilo aka 1,000
