Vibration sensors have a wide range of applications. In the industrial sector, they act like "industrial stethoscopes," monitoring the operating status of machinery and equipment. For example, installing vibration sensors on large generator sets, fans, compressors, and other equipment allows for real-time monitoring of vibration, enabling the timely detection of potential malfunctions and preventing production stoppages due to equipment damage. In the automotive industry, they are used to detect vibrations in components such as car engines and chassis, helping engineers optimize designs and improve driving comfort and safety. In structural health monitoring of bridges and buildings, vibration sensors can monitor building vibrations in real time, providing timely warnings upon detecting abnormalities and protecting people's lives and property. Even in the smart home field, they can play a significant role, for example, sensing abnormal vibrations in doors and windows and issuing timely alarms to safeguard home security.
