Magnetic Sensors are special types of sensors used to measure the magnetic fields of an object. Linear, Compass and ICs are the three types of magnetic sensors. Each type has its own application field and working principle as discussed in this article.

Linear magnetic sensors are primarily used to measure changes in the strength and direction of a magnetic field. These sensors come in the form of contactless devices and require three components: a sensor, an analog-to-digital converter and processor. The sensor is typically a coil of wire that interacts with a magnetic field to generate a voltage. The voltage is then sent to the analog-to-digital converter that converts the voltage into a numerical value that can be processed by the processor. Linear magnetic sensors are most commonly used for industrial automation and robotics applications.

Compass magnetic sensors are used to measure and detect the direction of a magnetic field. These sensors typically consist of a digital compass, magnetometer, and an interface circuit. The magnetometer is the component that interacts with the magnetic field. It is typically composed of a coil of wire that produces a voltage that is proportional to the strength of the magnetic field. The voltage is then sent to the digital compass, which uses the voltage to determine the direction of the magnetic field relative to the sensor\'s orientation. Compass magnetic sensors can be found in applications such as mobile phones, drones, and autonomous cars.

Integrated circuit (IC) magnetic sensors are used to detect and measure both changes in the strength and direction of a magnetic field. The sensing element of an IC magnetic sensor is typically a magnetic tunnel junction (MTJ). The MTJ consists of two ferromagnetic plates separated by a thin insulating barrier. When exposed to a magnetic field, the MTJ produces a resistance that is proportional to the strength and direction of the magnetic field. The resistance is then processed by the IC to generate a digital output that can be used by the user for further analysis or control.

In conclusion, the three types of magnetic sensors have their own application fields and working principles. Linear magnetic sensors are used to measure changes in the strength and direction of a magnetic field while compass magnetic sensors are used to measure and detect the direction of a magnetic field. Finally, IC magnetic sensors are used to detect and measure both changes in the strength and direction of a magnetic field. Therefore, users can choose the appropriate type of magnetic sensor for their application depending on the type of information they need.
