A "magnetic sensor" is a device designed to detect and measure magnetic fields in its vicinity. It functions by converting the magnetic field strength into an electrical signal or another readable output. These sensors are utilized in various applications to detect the presence, strength, or changes in magnetic fields. Magnetic sensors come in different types, including Hall-effect sensors, magnetoresistive sensors, and fluxgate sensors. Hall-effect sensors, for instance, utilize the Hall effect to produce a voltage proportional to the magnetic field strength. Magnetoresistive sensors rely on changes in electrical resistance due to magnetic fields, and fluxgate sensors measure the flux density of magnetic fields. These sensors find widespread use in automotive systems, industrial machinery, consumer electronics, and medical devices. In automotive applications, magnetic sensors are employed in speedometers, ABS systems, and position sensing. In industrial settings, they contribute to applications such as proximity sensing, motor control, and navigation systems. The versatility of magnetic sensors makes them integral in various technologies requiring accurate detection and measurement of magnetic fields.
