Can some body help me, please

I need idea for scanning position pulsa of stepper motor.
Motor bipolar 1.8 deg. Controller 89s51
please help me

I heve an idea. By using just four npn transistors you should be able to detect even slow movements. But this works best if the stepper has a rated voltage being as high as possible - 24V is good.

But then again - problem is that it will probably be too sensible or that it can miss a movement.

Therefore, dear dimas_lilik should use an encoder to measure the position. Or else any noise, slow movement can disturb an useful signal.
