Acceleration sensors, also known as accelerometers, are devices that measure the rate of change of velocity of an object. They detect changes in motion or orientation by sensing acceleration forces, which can be static, like gravity, or dynamic, caused by movement. These sensors are commonly used in various applications, including smartphones, fitness trackers, and automotive systems. In addition to consumer electronics, acceleration sensors play a crucial role in industrial and aerospace applications. They help monitor vibrations in machinery, enhance navigation systems, and improve safety features in vehicles. By providing real-time data on motion, these sensors contribute to better performance and reliability in many technologies.
