Hall effect sensor Electricity - Magnetism
A Hall effect sensor (or simply Hall sensor) is a type of sensor which detects the presence and magnitude of a magnetic field using the Hall effect. The output voltage of a Hall sensor is directly proportional to the strength of the field. It is named for the American physicist Edwin Hall. Hall sensors are used for … See more In a Hall sensor, a current is applied to a thin strip of metal. In the presence of a magnetic field perpendicular to the direction of the current, the charge carriers are deflected by the Lorentz force, producing a … See more A Hall probe is a device that uses a calibrated Hall effect sensor to directly measure the strength of a magnetic field. Since magnetic … See more Hall sensors are linear transducers. Such sensors require a linear circuit for processing the sensor output signal. This circuit provides the drive voltage for the sensor and is used … See more Position sensing One of the most common industrial applications of Hall sensors used as binary switches is in position sensing. Hall sensors are also used in brushless DC motors to sense the position of the rotor and to switch the … See more The key factor determining sensitivity of Hall effect sensors is high electron mobility.
