A Hall effect sensor (also known as a Hall sensor or Hall probe) is any sensor incorporating one or more Hall elements, each of which produces a voltage proportional to one axial component of the magnetic field vector B using the Hall effect (named for physicist Edwin Hall).
The Hall effect is the production of a potential difference (the Hall voltage) across an electrical conductor that is transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879. [1] [2]
The hall effect sensor is a type of magnetic sensor which can be used for detecting the strength and direction of a magnetic field produced from a permanent magnet or an electromagnet with its output varying in proportion to the strength of the magnetic field being detected.
Hall effect sensor (suitable for AC, DC, or pulsating current), a type of current sensor which is based on the Hall Effect phenomenon discovered by Edwin Hall in 1879.
Jun 7, 2024 · 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 Effect sensors, classified as transducers, play a crucial role in detecting and gauging magnetic fields. Their fundamental principle involves the generation of an output voltage when exposed to a magnetic field, thereby converting magnetic information into an electrical signal that can be conveniently processed and examined.
The Hall Effect is the most common method of measuring magnetic field and the Hall Effect sensors are very popular and have many contemporary applications. For example, they can be found in vehicles as wheel speed sensors as well as crankshaft or camshaft position sensors.
Oct 13, 2021 · This tutorial aims at providing a comprehensive insight into the interdisciplinary world of Hall-effect current sensors, encompassing the fundamental principles of operation, the design of the semiconductor device, the implementation techniques, as well as the methods for sensor modeling and characterization.
As you can tell from the name, the Hall Effect Sensor takes advantage of the phenomenon known as the Hall Effect. The Hall Effect refers to the potential difference (Hall voltage) on opposite sides of a thin sheet of conducting or semiconducting material through which an electric current is flowing, created by a magnetic field applied ...
This section describes common applications for Hall-effect sensors. Each use case details the type of sensor being used, how the sensor is implemented, device recommendations, and application-based documents to consider.
