  2. Hall effect sensor - Wikipedia

    en.wikipedia.org/wiki/Hall_effect_sensor

    A Hall probe is a device that uses a calibrated Hall effect sensor to directly measure the strength of a magnetic field. Since magnetic fields have a direction as well as a magnitude, the results from a Hall probe are dependent on the orientation, as well as the position, of the probe.

    en.wikipedia.org/wiki/Planar_Hall_sensor

    The planar Hall sensor is a type of magnetic sensor based on the planar Hall effect of ferromagnetic materials. [1] [2] It measures the change in anisotropic magnetoresistance caused by an external magnetic field in the Hall geometry. As opposed to an ordinary Hall sensor, which measures field components perpendicular to the sensor plane, the ...

    A Hall effect sensor uses the Hall effect to measure the magnitude of a magnetic field. Other languages Čeština: Animace funkce Hallovy sondy využívající Hallova jevu k měření intenzity magnetického pole .

  5. Hall effect - Wikipedia

    en.wikipedia.org/wiki/Hall_effect

    The term ordinary Hall effect can be used to distinguish the effect described in the introduction from a related effect which occurs across a void or hole in a semiconductor or metal plate when current is injected via contacts that lie on the boundary or edge of the void. The charge then flows outside the void, within the metal or semiconductor ...

  6. Current sensing - Wikipedia

    en.wikipedia.org/wiki/Current_sensing

    Fluxgate sensors or saturable inductor current sensors work on the same measurement principle as Hall-effect-based current sensors: the magnetic field created by the primary current to be measured is detected by a specific sensing element. The design of the saturable inductor current sensor is similar to that of a closed-loop Hall-effect ...

    en.wikipedia.org/wiki/Reed_switch

    The reed is hermetically sealed and can therefore operate in almost any environment, such as where flammable gas is present or where corrosion would affect open switch contacts. A reed switch has very low resistance when closed, typically as low as 0.05 ohms, whereas the Hall effect sensors can be in the hundreds of ohms. A reed switch requires ...

  9. Level sensor - Wikipedia

    en.wikipedia.org/wiki/Level_sensor

    A variation of magnetic sensing is the "Hall effect" sensor which utilizes the magnetic sensing of a mechanical gauge's indications. In a typical application, a magnetism-sensitive "Hall effect sensor" is affixed to a mechanical tank gauge that has a magnetized indicator needle, so as to detect the indicating position of the gauge's needle.
