Hall effect sensor

A Hall effect sensor is a device that detects magnetic fields. It operates based on the Hall effect, which occurs when an electric current flows through a conductor placed in a magnetic field, resulting in a voltage perpendicular to both the current and the magnetic field. This voltage change can be measured and used to determine the presence, strength, or direction of the magnetic field. Hall effect sensors are commonly found in various applications, including automotive systems for position sensing, smartphones for detecting screen orientation, and industrial equipment for monitoring magnetic devices.
