Vibration Sensor Module

Overview

This module features a highly sensitive vibration sensor and an on-board voltage comparator for producing a digital output signal.

When the vibration switch is under closed conduction state, the output signal is low and the green light is on. When the vibration switch is disconnected, the output signal is high and the green light is turned off.

It can be directly connected to a microcontroller for reading the output level and to easily determine the sensor state. The output of the sensor indicates whether vibration was detected in the environment.

The typical applications include theft alarms, earthquake alarms and more.
