霍尔元件是一种基于霍尔效应的磁场传感器,霍尔传感器利用导体和磁场相对运动,导体材料内部的载流子(电子、空穴)随磁场改变运动方向这一特性而制成的传感器,是体型磁电式传感器典型代表。本文阐述了霍尔传感器在自动检测和计数方面的较为先进的几个应用。
The Hall element is a Hall effect-based magnetic field sensor. The Hall sensor makes use of the relative movement of the conductor and the magnetic field, and the sensor (electron and hole) inside the conductor material to change the direction of the movement according to the magnetic field , Is a typical representative of bulk magnetic sensors. This article describes some of the more advanced Hall sensor applications in automatic detection and counting.
