Fast Response Hall Effect Current Sensor Small Size Light Weight Easy Installation
The Hall sensor is a magnetic field sensor made according to the Hall effect. Hall effect is a kind of magnetoelectric effect. This phenomenon was discovered by Hall (A.H.Hall, 1855-1938) in 1879 when he was studying the conductive mechanism of metals. Later, it was found that semiconductors and conductive fluids also have this effect, and the Hall effect of semiconductors is much stronger than that of metals. Various Hall elements made of this phenomenon are widely used in industrial automation technology, detection technology and information processing, etc. aspect. The Hall effect is a basic method for studying the properties of semiconductor materials. The Hall coefficient measured by the Hall effect experiment can determine important parameters such as the conductivity type, carrier concentration, and carrier mobility of semiconductor materials.
