Hello all, buntay again with a question that I am not completely sure about.
Application: I have a coal bin I would like to monitor the level of. I am planning on using 10, evenly spaced, 6-30Vdc PNP capacitive prox sensors and will be powering them with 12V.
Problem: I would like to use 1 input pin of a 20X2 as an adc to get the level based on the different voltages.
Now, I am sure this is possible by using a voltage divider in series setup but what I am not sure of is what this schematic would look like. Now I dont need values of the resistors unless someone would like to provide them...hahaha. could someone post what this schematic would look like?
Thanks
F.
