Accelerometer

An accelerometer is a device that detects and measures changes in motion or position by sensing acceleration forces. It can identify movement in different directions—up and down, side to side, or forward and backward. These sensors are common in smartphones, fitness trackers, and vehicles, enabling features like screen rotation, step counting, and stability control. Essentially, an accelerometer translates physical movement into electronic signals, helping devices understand how they are moving or positioned in space, which allows for responsive and dynamic functionalities.
