Vibration Sensor Module for Shock Detection

The Vibration Sensor Module for Shock Detection uses an onboard LM393 comparator with an adjustable potentiometer, giving a digital switch output (0 or 1), operating from 3.3V to 5V, compatible with Arduino. An installation advantage of this vibration sensor over tilt-based sensors covered separately is orientation independence — the vibration sensing element responds to mechanical shock and movement regardless of which way up the module is mounted, unlike ball-tilt switches that only trigger when oriented relative to gravity in a specific direction.

The vibration sensor module’s LM393 comparator output stage can directly drive a transistor or small relay in addition to signaling a microcontroller input, making this vibration module capable of acting as a standalone shock-triggered switch without needing any Arduino code at all when wired directly to a relay coil through a transistor buffer. This makes the shock detector sensor useful in simple standalone alarm circuits where a microcontroller is overkill for the application.

while orientation independence is an advantage, this means the vibration sensor price reflects a module that cannot differentiate between vibration from the monitored surface and vibration transmitted from nearby machinery or foot traffic through the mounting structure, making rigid isolation mounting or software debouncing important in high-vibration environments. Available from StemVolt, this module is ideal for hobbyists, and makers building orientation-independent shock detection systems and standalone vibration projects.
