The Vibration module is based on the vibration sensor SW-420 and Comparator LM393 to detect if there is any vibration beyond the threshold. The threshold can be adjusted by the onboard potentiometer.

When this no vibration, this module output logic LOW the signal indicate LED light, and vice versa.
