What is a Angular rate sensor?

An angular velocity sensor, also called a gyro sensor, detects the amount of change in angle per second. By using this sensor, it is possible to detect the posture, orientation, vibration, etc. of an object. In automobiles, it is also used for vehicle position detection in car navigation systems, turning speed detection for skid prevention devices, and image stabilization for smartphones and digital cameras. The main types of gyro sensors are rotating mechanical, vibration, and optical, and it is necessary to select one according to the application.
