Vibration Sensor (normally off)

Simple to use vibration sensor module. Comes with SW-420 vibration sensor, integrated with adjustable sensitivity via on board potentiometer. And there are LED indicators for power and also digital output status. Simple and straight forward interface, just 3-pin, VCC, GND and the DO (digital output). Support 3.3V or 5V power.

This vibration sensor module is compatible with any microcontroller that have digital input. Of course popular microcontroller such and PIC, Arduino, Raspberry Pi are compatible. Direct interface is essential to use this sensor.

The DO will be logic LOW when there is no vibration, and indicator LED will light.

Example of applications:

• Vibration detecting
• Burglary protection system
