what is hall effect sensor ?
Electronics Projects : A Hall effect sensor is a type of transducer that detects the presence of a magnetic field. It works based on the Hall effect, which is the production of a voltage difference (Hall voltage) across an electrical conductor (such as a semiconductor) when subjected to a magnetic field perpendicular to the current flow. Here's how a Hall effect sensor works and its typical applications: Working Principle: Hall Effect : When a conductor carrying current is placed in a magnetic field perpendicular to the current flow, the Lorentz force causes electrons to accumulate on one side of the conductor, creating a measurable voltage difference perpendicular to both the current and the magnetic field. This phenomenon is known as the Hall effect. Sensor Configuration : A Hall effect sensor typically consists of a thin strip of semiconductor material (e.g., gallium arsenide) through which a current flows. The sensor is mounted in such a way that a magnetic field can be appl
