AA002-02E Application Field and Working Principle

Magnetic sensors are devices that measure magnetic fields. They are often used to detect the presence of a magnetic field, as well as to measure its strength. AA002-02E is a particular type of magnetic sensor that falls under the category of linear, compass sensors (ICs). It is applicable to a wide range of applications, ranging from navigation, automotive, and satellite communication systems to detect and compute the direction and relative orientation of objects.

Applications of AA002-02E

AA002-02E is a commonly-used sensor type due to its small size and robustness against variations of magnetic field strength, making it applicable for a variety of applications. In automotive applications, this type of sensor helps improve steering, alignment, and stabilization systems. In the navigation sector, AA002-02E is used in inertial navigation systems to provide precise positioning information. On platforms such as aircraft, it assists in maintaining altitude and heading awareness when navigating from one point to the other. In addition, AA002-02E is also suitable in other cases such as drone/robot guidance systems.

Working Principle

AA002-02E utilizes a magnetic field sensing technology called Anisotropic Magnetoresistance (AMR). This technology is based on the principle that the electrical resistance of a material changes when the direction of a magnetic field changes. In the AA002-02E, the resistance is sensitive to the three main axes, namely the x, y, and z axes. As the direction of the magnetic field changes, the resistance along each axis changes, allowing the sensor to detect and measure the strength and direction of the magnetic field.The sensor is built with a number of small sensing elements arranged on a silicon substrate placed inside a ferrite material. When a magnetic field is applied, the resistance of each sensing element varies depending on its orientation to the field. The varying resistances are then combined and analysed by a Signal Conditioning Circuit (SCC), which determines the strength and direction of the applied field.

Conclusion

AA002-02E is a magnetic sensor that falls under the category of linear, compass sensors (ICs). It is suitable for a wide range of applications, such as automotive, navigation systems, and drone/robot guidance systems. It utilizes the AMR (Anisotropic Magnetoresistance) technology, which measures the electrical resistances of different sensing elements arranged on a silicon substrate, combined with the analysis of the varying resistances done by a Signal Conditioning Circuit to determine the strength and direction of the magnetic field.
