Gentleman, I have a question.
Why we all use a hallsensor and not a opto like they do into the automotive ignitions.

I use for tests also a optosensor becourse hallsensors aren't acurate for testpurposes.
I need a real TTL-signal and not a wave like hallsensors do.
Maybe a reflection opto sensor can be use ?
