A vibration sensor module, or vibration switch, can also be used in an Arduino intelligent car.

It uses a SW-420 normally closed type vibration sensor.

The comparator's output signal has a clean waveform and is good, with a driving ability of >15mA.

Working voltage: 3.3V-5V

Output format: Digital switching output (0 and 1)

It includes bolt holes for easy installation.

Small plate PCB size: 3.2cm x 1.4cm

It uses a wide voltage LM393 comparator.
