The Hall sensor is a magnetic sensor based on the Hall effect.

The object with current is placed in the magnetic field. If the current direction and the direction of the magnetic field are perpendicular to each other, a lateral potential difference is generated in a direction perpendicular to both the magnetic field and the current direction. This phenomenon is called a Hall effect, and the generated potential difference is called Hall voltage.

A Hall device is fabricated using a semiconductor material that produces a significant Hall effect. As a magnetoelectric conversion element in a Hall sensor, electromagnetic measurement can be performed, such as measuring magnetic physical quantities and electric quantities such as magnetic field, current, and electric power.

Hall sensors can also use the magnetic field as a medium to achieve non-contact measurement for many physical quantities. By measuring the non-electricity such as force, displacement, vibration, acceleration, speed, flow, etc., it is widely used in industry, transportation, communication, automatic control, home. Electrical appliances and other fields.
