I think you need to find out for certain what sort of sensor you have and what sort of signal it outputs. Is it definitely a Hall effect sensor? I would have thought that an MVR sensor was more likely.
how can i test to see if it is a mvr sensor?
a lot of the cars had a hall sensor looking at a steel trigger wheel for the engine rpm, so i thought these might be the same
so i will be easier to put some hall sensor on it like in link then?
ahh yes there is a pos and neg symbol just above the pins on the sensor that would explain why they are there so how do i intergrate that with the arduino?trying to find out information about it is near enough impossible ans manufacturers keep that information to themselves
