I have conducted an experiment to measure the changes in voltage/current due to the resistance changes of a photocell present in an LDR.
I wanted to know how I could use those values in order to calculate the illuminance present on the surface of the photocell.
I did not use a voltage differential circuit.
I looked at some websites and all the related experiments were simply using differential circuits.

Is there an LDR resistance to luminance conversion equation or something similar.
