3.3-5V 3-Wire Vibration Sensor Module

This module has a component that is able to detect the vibrations. Depending on the strength of the vibrations, using the built-in comparator on its outputs gives either digital (HIGH / LOW) or analog (0V-5V) signal.


Features

• Comparative output, clean signal, good waveform, strong driving ability, more than 15mA.
• Working voltage: 3.3V to 5V
• Output form: digital switch output (0 and 1)
• Equipped with fixed screw hole, easy to install
• PCB board size: 32mm x 14mm
• Uses the LM393 wide voltage comparator

When the VCC and GND are connected, the power indicator will light up.

Put the module on the desktop, adjust the blue potentiometer on the board until the on-board switch indicator lights up, and then slightly turn back the potentiometer untill the indicator light turns off. Hit the desktop with your hand so the vibration shocks the sensor, the indicator light will go on. Vibration stops, indicator light will turn off.
