Hall Effect Sensors are magnetic field sensors made based on the Hall effect. When a constant current flows through the internal Hall semiconductor chip, a potential difference, known as Hall voltage, is generated in the perpendicular direction. This Hall voltage changes with the strength of the magnetic field; the stronger the magnetic field, the higher … Read more
