The Hall sensor is a magnetic sensor based on the Hall effect that can be used to measure magnetic field strength and current strength. Its working principle is to control current at both ends of a metal or semiconductor sheet and apply magnetic induction intensity in the vertical direction of the sheet, then an electromotive force will be generated in the direction perpendicular to the direction of the current and magnetic field. This electromotive force is called the Hall voltage, and the magnetic field strength or current strength can be measured by measuring this voltage.
