Technical details and manufacturing context for Accelerometer

Definition
An accelerometer is a motion sensor component that detects and measures acceleration forces, including static gravity and dynamic motion-induced forces. Within motion sensor systems, it provides precise measurement of vibration, tilt, shock, and movement in various industrial applications.
Working Principle
Accelerometers typically operate using microelectromechanical systems (MEMS) technology, where a proof mass suspended by springs moves relative to fixed electrodes when acceleration occurs. This movement changes capacitance, which is converted to an electrical signal proportional to acceleration.
