accelerometer
含义: An instrument that measures the rate of change of velocity of an object, detecting acceleration forces including gravity, vibration, and movement.
Accelerometers are found in everything from aircraft inertial navigation systems to fitness trackers and smartphones, where they enable screen rotation and step counting. In engineering, they are used to monitor structural vibrations in bridges and buildings. The data they produce is measured in units of g-force. They are frequently paired with gyroscopes in inertial measurement units.
