Magnetic sensors

Magnetic sensors are devices that convert changes in the magnetic properties of sensitive components caused by external factors such as magnetic field, current, stress-strain, temperature, and light into electrical signals to detect corresponding physical quantities. Magnetic sensors are divided into three categories: compass, magnetic field sensor, and position sensor. Compass: The Earth generates a magnetic field, and if you can measure the magnetic field on the Earth's surface, you can use it as a compass. Current sensor: Current sensors are also magnetic field sensors. Current sensors can be used in household appliances, smart grids, electric vehicles, wind power generation, and more. Position sensor: If there is a position change between a magnet and a magnetic sensor, and the position change is linear, it is a linear sensor. If it rotates, it is a rotational sensor. A Hall sensor is a transducer that converts changing magnetic fields into changes in output voltage.
