Question

Why hall sensor dows not detect earth magnetic field?

Answer 1

⚡Ur Answer⚡


✨A Hall effect sensor is a transducer that varies its output voltage in response to a magnetic field.
✔✔ Hall effect sensors are used for proximity switching, positioning, speed detection, and current sensing applications

✨. ... In its simplest form, the sensor operates as an analog transducer, directly returning a voltage.


♨While the earth's magnetic field can be detected, it isn't usually wanted and could be a nuisance. For that reason strong magnets and low sensitivity hall sensors are used. ...

✨With a single axis hall effect sensor the maximum sensitivity will be when themagnetic field is perpendicular to the current flow.

Answer 2

$\mathfrak{The\:Answer\:is}$

Hall Effect Sensors. Magnetic sensors are typically Hall effect sensors(named after Edwin Hall who discovered the effect in 1879), whereby a small voltage difference canbe measured across a conductor with current flowing through it when a perpendicular magnetic field isapplied.
