The Hall element is a discrete structure, while the Hall integrated circuit is a circuit structure that makes the Hall element and the amplifier on a piece of semiconductor material. As an important branch of the modern sensor industry, magnetic sensors have been widely used in industry, national defense, science and technology, and medical fields. They are mainly used in modern industry and electronic products to sense magnetic field strength to measure physical parameters such as current, position, and direction. Among the existing technologies, there are different types of sensors used to measure magnetic fields or other parameters.
