motion

Motion sensors

The motion module gives access to the device’s accelerometer, gyroscope and magnetometer data.

Functions

motion.start_updating()

Starts receiving information from the sensors.

motion.stop_updating()

Stops receiving information from the sensors

motion.get_acceleration() → motion.Acceleration

Returns a tuple with information about acceleration (x, y, z).

Return type:Acceleration

motion.get_attitude() → motion.Attitude

Returns a tuple with information about the attitude (roll, pitch, yaw).

Return type:Attitude

motion.get_gravity() → motion.Gravity

Returns a tuple with information about gravity (x, y, z).

Return type:Gravity

motion.get_magnetic_field() → motion.MagneticField

Returns a tuple with information about the magnetic field (x, y, z).

Return type:MagneticField

motion.get_rotation() → motion.Rotation

Returns a tuple with information about rotation (x, y, z).

Return type:Rotation
