Working principle of Hall throttle position sensor

Apply current. According to the query of Huaqiang Electronic Network, the Hall throttle position sensor is based on the Hall effect, that is, when the current passes through the semiconductor perpendicular to the external magnetic field, the carriers deflect, generating an additional electric field perpendicular to the direction of the current and the magnetic field, thus generating a potential difference across the semiconductor. The semiconductor applies a current perpendicular to the magnetic field and produces a voltage perpendicular to the current direction on the semiconductor plane. The output voltage is proportional to the magnetic field strength.
