WebMay 20, 2016 · For the case of a material with one dominant carrier, the Hall coefficient is inversely proportional to the carrier density. ... carriers, the smaller the Hall coefficient and the smaller the Hall voltage which must be measured. The scattering factor r depends on the scattering mechanisms in the material and typically lies between 1 and 2. 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 c…
