Magnetic Sensors are devices that can detect magnetic fields and their changes, obtaining information by sensing the strength, direction, or presence of a magnetic field. This conversion process allows the magnetic sensor to accurately capture and identify parameters such as magnetic field strength and direction, thus achieving sensitive monitoring of the physical environment. This kind of sensor works based on the physical principle of magnetoresistance effect, Hall effect, giant magnetoresistance effect, etc., and converts the magnetic field change into electrical signal output, so as to realize the measurement and analysis of the magnetic field. It can measure static or dynamic magnetic fields and convert them into electrical signals in the form of voltage and current, which is convenient for subsequent data processing and analysis. This characteristic makes the magnetic sensor play an irreplaceable role in automatic control, computer information processing, security control and other fields.

Magnetic Sensors: The role of Magnetic Sensors is mainly reflected in two aspects: first, it is used for direct measurement of magnetic field, such as magnetic field strength meter, fluxgate, etc., for studying the Earth magnetic field, detecting the magnetism of materials, etc.; The second is as an indirect measurement tool of position, Angle or speed, by sensing the position change or rotation Angle of external magnets, applied to non-contact switches, encoders, speed sensors and other occasions. In terms of application areas, magnetic sensors show their diversity and flexibility. In industrial automation, magnetic sensors are often used for motor control, speed measurement and position detection to ensure the stable operation of production lines. In the field of automotive electronics, magnetic sensors are used for real-time monitoring of speed, inclination, Angle and other parameters to improve driving safety and comfort. In addition, in medical equipment, aerospace, consumer electronics and other fields, magnetic sensors also play an important role, such as used in ventilators, navigation equipment, electronic compasses and other products.
