Modul SW420 sw 420 senzor de vibratie miscare switch alarm sensor module Arduino

Purpose:

Used to trigger the effect of various vibration, theft alarm, intelligent car, earthquake alarm, motorcycle alarm, etc.

This module is compared with the normally open type vibration sensor module, vibration trigger for longer periods of time, can drive the relay module.

Module directions for use:

1. product no vibration, vibration switch is closed on state, the output terminal output low level, the green light is lit.

2. product vibration, the vibration switch instantaneous disconnection, output the output high level, the green light is not bright.

3. output can be directly connected to microcontroller, through single chip microcomputer to detect the high and low level, thus to detect whether there is a vibration environment, call the police.
