An accelerometer measures proper acceleration, which is the acceleration it experiences relative to freefall and is the acceleration felt by people and objects. [2]

Accelerometer, instrument that measures the rate at which the velocity of an object is changing (i.e., its acceleration). Acceleration cannot be measured directly. An accelerometer, therefore, measures the …

Accelerometer sensors are inertial sensors that measures the change in velocity (acceleration) of an object over time. They are used in a variety of applications, including automobiles, smartphones, …

Accelerometers are devices that measure acceleration, which is the rate of change of the velocity of an object. They measure in meters per second squared (m/s 2) or in G-forces (g).

What is an accelerometer? An accelerometer is a device that measures the vibration, or acceleration of motion of a structure.
