SW-420 Vibration Sensor Module

The Vibration module based on the vibration sensor SW-420 and Comparator LM393 to detect if there is any vibration that beyond the threshold. The threshold can be adjusted by the on-board potentiometer. When this no vibration, this module output logic LOW the signal indicate LED light,And vice versa.

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

• Product no vibration, vibration switch is closed on state, the output terminal output low level, the green light is lit
• Product vibration, the vibration switch instantaneous disconnection, output the output high level, the green light is not bright
• 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>
