I want to check if my car lamps are properly working or not, without interfering with or modifying the electrical plant of the car, so I thought about using hall current sensors... but I don't know anything about them, so I can't understand their datasheets.
I see they give out a voltage proportional to detected current, or a digital signal, which is what I actually need, as I want to interface them to a PIC.
So, which specific hall sensor should I buy? I think current I have to detect is about 1 or 2 A (car bulbs).
As I said, I don't want to modify my car, so a shunt resistor is out of the scope.
