Purpose:
Used to trigger various vibration, theft alarm, intelligent car, earthquake alarm, motorcycle alarm, etc.
This module can drive vibration triggers and relay modules for longer periods of time compared to normal vibration sensor modules.
Direction of the module used:
1. Unmatched vibration, vibration switch is closed to the ON state, output terminal is low level, green light is illuminated.
2. Product vibration, vibration switch instantly, output output high level, green light not bright
3. It can detect high and low levels directly, and to detect whether there is a vibration environment, you can connect the microcontroller via a phone single chip microcomputer.
