Vibration Sensor Module (SW-420)

This module features an adjustable potentiometer, a vibration sensor, and an LM393 comparator chip to give an adjustable digital output based on the amount of vibration. The potentiometer can be adjusted to both increase and decrease the sensitivity to the desired amount. The module outputs a logic level high (VCC) when it is triggered and a low (GND) when it isn’t. Additionally, there is an onboard LED that turns on when the module is triggered.
