NOTE:
The Double Feed Sensor PCB uses an ultrasonic sensor. With the ultrasonic method, the oscillation portion emits ultrasonic wave
to the paper surface. In the result, new ultrasonic wave is generated as the paper vibrates, and the reception side reads the
ultrasonic wave. A double feed is detected when the oscillation is smaller due to a second sheet of paper.
