SENSOR_CATEGORY_MOTION

  • Article

The SENSOR_CATEGORY_MOTION category contains sensors that provide information that is related to physical movement. Accelerometers measure acceleration of the sensor, including gravitational acceleration. Motion detectors, such as human movement detection in a security system, sense moving objects. Gyrometers sense changes in angular velocity. Speedometers measure velocity.
