Dropping the voltage divider and measuring the current through a current mirror generates a linear voltage across its output load resistor that can be easily read by your microprocessor.

By carefully selecting the resistor values, you can ensure the output voltage meets the specific requirements of your circuit. Figure caption, A potential divider (or voltage divider), circuit ...
