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 proximity sensing, positioning, speed detection, and cu… Webb29 juli 2009 · Hall-Effect Sensors: Theory and Applications by Edward Ramsden. Newnes, 2006.
