What Is A Hall Sensor

Hall effect sensor, also called Hall sensor, is a transducer that converts a changing magnetic field into a change in output voltage. Hall sensors are first and foremost used to measure magnetic fields. In addition, they can measure physical quantities that generate and affect magnetic fields, such as proximity switches, halls, position measurement, rotational speed measurement, and current measurement equipment. In its simplest form, the sensor acts as an analog transducer and returns a voltage directly. Under a known magnetic field, its distance from the Hall disk can be set. Using multiple sets of sensors, the relative position of the magnet can be inferred. The current through the conductor will produce a magnetic field that changes with the current, and the Hall effect sensor can measure the current without disturbing the current. The typical structure is to integrate it with the winding core or the permanent magnet beside the conductor .
