Recently I have asked a question, why my sensors do not work on external power supply (link). I have found out, that I was limiting the current too much with the resistors. I have tried using two sensors:
My logic is, if they are rated at that current, I should put a resistor in the Vin, to restrict the current to given value. But it turned out that I was wrong, because they started working only after I removed my resistors.
My questions is - should I put a resistor in there? If yes, then how do I know what resistance should I have, if the data sheet values are misleading?
