An electronic compass determines the direction of north, similar to a magnetic compass. Most electronic compasses do this not only in the X/Y direction, but also three-dimensionally in the X/Z and Y/Z directions.
Applications
- Aircraft construction
- Drones and similar
- Navigation
- Car manufacturing
- Smartphones
- Satellites
How it works
An electronic compass is also called a magnetometer. It is based on the Hall effect. When a current-carrying conductor encounters a magnetic field, the electrons within it are deflected, leading to a change in voltage. This voltage change can be measured, and from it, the magnetic field can be determined. Modern electronic compass sensors are constructed from thin films within an IC package, which can perceive and measure the Earth's magnetic field.

Hello,
Thanks for explaining the electronic compass. Just a note:
The underlying effect was discovered by Edwin Hall and is therefore also called the Hall effect.
Kind regards from Physy
Hello Hans,
Thank you very much for your contribution and your tip. I've corrected it.
