Hall effect is a sensor which is use to sense the magnetic field with out any physical connection to the magnetic field generating object. It operate in such a way that when a current carrying conductor is placed in a magnetic field it it induce a voltage in a conductor which will be perpendicular to the magnetic field and current.
