In my project I need to read the resistance of sensors which are connected to 12V. The resistance range is quite wide, some of them are 0-1000ohm, some 0-50kohm. I made some calculations and I need to switch between 50ohm, 1000ohm and 1000kohm resistors. The first idea is to use digipot, but they are linear. Is there any simple application to switch resistors? Or maybe there is a different way to read resistive sensors?
Please give me some advice, thanks in advance
