The Knock Sensor Module

Detects knocks and vibrations using a piezoelectric sensor.

Converts mechanical vibration into an electrical signal.

Operates typically at 3.3V or 5V.

Provides digital output (some versions also offer analog output).

Commonly used in Arduino projects, alarms, and tap-detection systems.
