AK8973 is a type of magnetic sensor / linear, compass IC (Integrated Circuit) designed for mobile applications. It can detect the direction, magnitude, and angle of magnetic fields, and can be interfaced with microcontrollers, CPUs, and other digital devices. In this article, we will discuss in detail the application field and working principle of AK8973.

Application fields

With its ability to detect the direction, magnitude, and angle of magnetic fields, AK8973 is mainly used in the fields such as navigation, mapping, designing, and vehicle intelligent guidance systems. In addition, it can be used as a graphical user interface (GUI) for various multimedia applications such as gaming consoles and virtual reality headsets.

AK8973 is also widely used in various vehicle tracking systems and digital compass systems. It allows users to track the real-time location of their vehicle, as well as determine its direction and orientation. Furthermore, it can be used in aviation navigation systems and in military applications such as earth observation systems and radio wave propagation calculations.

Working principle

AK8973 uses Hall effect transducers to measure the intensity and direction of a magnetic field. The Hall effect transducer acts as a bridge between the magnetic field and the electrical circuit. When a magnetic field passes through the transducers, it creates a potential difference which can be measured by the circuit. This voltage can then be used to determine the magnitude, direction, and angle of the magnetic field.

Once the voltage is measured, it is fed into the analog to digital converter (ADC) which converts the analog signal into digital data. This digital data is then used to determine the direction, magnitude, and angle of the magnetic field. Finally, this data can be used to control the movement of robots or to calculate the orientation or location of the robot.

The AK8973 is a versatile magnetic sensor that can be used in a variety of applications. Its ability to detect the direction, magnitude, and angle of a magnetic field makes it a powerful tool in navigation, mapping, and designing applications. In addition, its capability to output digital data makes it easy to integrate with various microcontrollers and CPUs.
