霍尔传感器是基于霍尔效应的一种传感器。是利用半导体材料的霍尔效应进行测量的一种磁敏式传感器。它可以直接测量磁场和微位移量,应用于电池测量、压力、加速度、振动等方面的测量领域。霍尔传感器已从分立元件发展到集成电路的阶段,正越来越受人们的重视,应用日益广泛。 应用范围: 电子式水表、气表、电表和远程抄表系统...
But there's a simple way to measure magnetism with a device called a Hall-effect sensor or probe, which uses a clever bit of science discovered in 1879 by American physicist Edwin H. Hall (1855–1938). Hall's work was ingenious and years ahead of its time—20 years before the ...
of a magnetic field, a voltage is generated across it. He found that this voltage, now named after him, is proportional to the vector cross product of the current flowing through the sensor and the magnetic field. The proportionality constant γ is a property of the Hall Effect sensor....
