Accelerometer

An accelerometer is an instrument or sensor that measures acceleration, which is the rate of change of velocity of an object over time. It can detect changes in motion or orientation, typically in three-dimensional space (x, y, and z axes). Accelerometers are commonly used in various applications, including smartphones, fitness trackers, automotive systems, and aerospace technologies, to monitor movement, detect orientation, and enable features like screen rotation and motion-based controls. The device works by measuring the forces acting on a mass within the sensor, which allows it to calculate the object's acceleration relative to gravity.
