Magnetic field sensor

A magnetic field sensor is a device that detects the presence and strength of magnetic fields. It works by measuring the magnetic forces that arise from magnets or electrical currents. These sensors are commonly used in various applications, such as in smartphones for compass functions, in automotive systems for detecting position, and in industrial equipment for monitoring machinery. They can provide valuable data for navigation, location tracking, and even security systems. Magnetic field sensors come in different types, like Hall effect sensors and magnetoresistive sensors, each suited for specific uses based on sensitivity and range.
