- The accelerometer allows us to measure the acceleration of a body and to have its graphical depiction of time or the values given to us by other sensors we use.
- The gyroscope is a device that can maintain its orientation constant by rotating its parts and the principle of maintaining the spin.
- The magnetometer is a suitable instrument for measuring Earth's magnetism.
- The compass is an instrument that guides the user, pointing it in the North direction.
- Inertial Measurement Unit (IMU) is an electronic device that measures and reports the specific strength of the body, angular velocity and sometimes the magnetic field surrounding the body, using a combination of accelerometers and gyroscopes, sometimes magnetometers.
