Crank Position Sensor Signal Amplification and Display

#CKP sensor-signal oscilloscope opamp

To find DC motor RPM, We have to insert a metal disc with teeth, then the Crank Position Sensor placed neared to the disc. When the crank position sensor is placed near a rotating metal disc with teeth, it generates a small analog voltage signal, it can be amplified using opamp. Then it displays through an oscilloscope.

Simply we used a crank position sensor circuit to measure the RPM of a DC motor.
