Hall effect sensor

<p>A Hall effect sensor (also known as a Hall sensor or Hall probe) is any <a href="/facts/Sensor/RN8SXbjs">sensor</a> incorporating one or more Hall elements, each of which produces a <a href="/facts/Voltage/EN2po6N2">voltage</a> proportional to one axial component of the <a href="/facts/Magnetic_field/Ta8Ev588">magnetic field vector B</a> using the <a href="/facts/Hall_effect/4r86ffPr">Hall effect</a> (named for physicist <a href="/facts/Edwin_Hall/HnHW32PR">Edwin Hall</a>).
</p><p>Hall sensors are used for <a href="/facts/Proximity_sensing/vmjXXDJh">proximity sensing</a>, <a href="/facts/Positioning_(navigation)/bSfNnXnK">positioning</a>, <a href="/facts/Speed_limit_enforcement/c344ShSm">speed detection</a>, and <a href="/facts/Current_sensing/xHEQuzpS">current sensing</a> applications and are common in industrial and consumer applications. Hundreds of millions of Hall sensor <a href="/facts/Integrated_circuits/fjn6vg7C">integrated circuits</a> (ICs) are sold each year by about 50 manufacturers, with the global market around a billion <a href="/facts/United_States_dollar/naEEDUhC">dollars</a>.
