The voltage you are seeing is, probably, a bias voltage. These sensors will produce their own AC voltage, and an AC sine wave. As speed increases, frequency and amplitude increase. Set you scope to AC coupling, with a time-base of 100-200 ms.

What voltage scale are you set on? Low wheel speed will be low voltage.

I ground the sensor.


What do you mean by this?
