Hall Effect Speed Sensor Working Principle

A Hall Effect speed sensor operates based on the principles of the Hall Effect, which involves a thin piece of rectangular p-type semiconductor material, such as gallium arsenide (GaAs), indium antimonide (InSb), or indium arsenide (InAs), through which a continuous current flows. When this semiconductor is placed within a magnetic field, the magnetic flux lines exert a force on the charge carriers (electrons and holes), causing them to deflect to either side of the semiconductor slab. This deflection results in a potential difference across the semiconductor material due to the build-up of charge carriers. The Hall Effect, named after Edwin Hall who discovered it in the 1870s, relies on the Lorentz force and requires the magnetic flux lines to be perpendicular to the current flow. The sensor detects the presence and magnitude of a magnetic field, typically turning “ON” (closed circuit) when exposed to a magnetic field of sufficient strength and correct polarity, and remaining “OFF” (open circuit) in the absence of such a field. This principle allows the Hall Effect sensor to provide information about the type of magnetic pole and the strength of the magnetic field, making it a crucial component in various applications, including speed sensing.
