### Vibration Sensor Overview

1. **Functionality**: Detects and measures vibrations or movements, converting them into electrical signals.

2. **Types**: Available in various forms, including piezoelectric, accelerometer, and spring-mass sensors, each suited for different sensitivity and applications.

3. **Applications**: Used in security systems, industrial machinery monitoring, and vibration analysis in structural health monitoring.

### Typical Uses:

- **Security Systems**: Detects unauthorized access or tampering through vibration detection.

- **Industrial Equipment**: Monitors machinery health by detecting unusual vibrations indicating potential faults.

- **Structural Monitoring**: Measures vibrations in buildings and bridges to assess structural integrity.
