Are the results for Proteus simulation and hardware testing for same purpose using different controllers comparable?
Proteus is highly unreliable in circuit simulation. Sure, you can run your code to check if its working or not but that is the extent of it. Never depend on any simulation results from Proteus. You said that you have modeled sensors as Voltage dividers which is exactly what I am talking about: You can check if changing the voltage has any effect or not and that maybe fine but do not make the mistake of comparing it to your hardware results. There will always be a big error in Proteus results. Trust me, I learned it the hard way.
