[[File:Hall sensor tach.gif|220x220px|thumb|Figure 1: a wheel containing two [[magnets]] passing by a Hall effect sensor. The voltage from the sensor peaks twice for each revolution. This arrangement is used to measure and regulate the speed of rotating objects, including [[Disk storage|disk drives]].]]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#The B-field|magnetic field vector {{math|'''B'''}}]] using the [[Hall effect]] (named for physicist [[Edwin Hall]]).
