So I tested installed HAL sensor on the Mow motor and signal is following :

when magnet is on hal, there is 0V :

and out of the hal 2,6V :

Not sure if this short pulses are enough for interrupt counting.

I found also other PCB with other HAL and signal is different :

What's your opinion ?

Thanks

I would assume that only the last signal will work. The first signal needs pre-processing by some circuit.
