Working principle
At current (IP=0A), the voltage of the output pin is half of the power supply voltage. When the current passes through the through hole in the middle of the sensor from the forward direction, the output voltage correspondingly increases. On the contrary, when the current passes through the middle hole of the sensor in the opposite direction, the output voltage correspondingly decreases, and the amplitude of the increase or decrease is symmetrical.
