What component is used to sense specific components of acceleration?

The component used to sense specific components of acceleration is an accelerometer. Accelerometers are devices that measure the rate of change of velocity over time. They detect acceleration forces, which can be static (like the continuous force of gravity) or dynamic (caused by motion or vibrations). This capability allows them to determine changes in motion or orientation of an object in all three axes—X, Y, and Z.

In many applications, such as smartphones, fitness trackers, and automotive systems, accelerometers play a crucial role in providing information about movement and orientation, which is essential for navigation, activity monitoring, and stability control. They are particularly effective for measuring linear acceleration and, when used in combination with other sensors, can provide comprehensive information about an object's motion profile.

The other components listed serve different purposes. For instance, gyroscopes measure angular velocity, and inclinometers assess angles of slope or tilt relative to gravity. Altimeters measure altitude, typically by detecting changes in air pressure. Each of these devices has its specific function and is not designed primarily to measure acceleration in the way that accelerometers do.
