Joes:
i tride that sensor out to day and could not get it to work the way we discussed so i tock the 10K pull down resister out and put a pot in then tork the pot down to 1.3k and it did work but very tempermental
the sensor seems to work between 1.0-1.3k
what do you think?
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.
