Magnetic sensors have become an essential component in modern electronic systems, enabling accurate detection and measurement of magnetic fields for a wide range of applications. These sensors convert magnetic field variations into electrical signals, allowing devices and systems to monitor position, speed, direction, current, and proximity with high precision.
The working principle of magnetic sensors is based on detecting changes in magnetic fields generated by permanent magnets, electric currents, or magnetic materials. Different sensing technologies are used depending on application requirements, including Hall-effect sensors, magnetoresistive sensors, fluxgate sensors, and inductive magnetic sensors.
