Vibration Sensor Module for Shock Detection

The Vibration Sensor Module for Shock Detection combines a vibration-sensing element with an onboard LM393 comparator and adjustable potentiometer, outputting a digital switch signal (0 or 1), operating from 3.3V to 5V, compatible with Arduino. The vibration sensor’s potentiometer works by setting a reference voltage inside the LM393 comparator circuit — when the vibration element’s signal crosses this adjustable threshold, the comparator output flips state, giving a clean trigger rather than a noisy raw analog signal.

The vibration sensor module’s tuning workflow in practice involves starting with the potentiometer at a moderate setting, testing with expected vibration levels, then turning it clockwise or counterclockwise to raise or lower sensitivity until the module reliably triggers only on genuine shock events rather than ambient building or machinery vibration. This vibration module’s digital output integrates directly with an Arduino interrupt pin for instant event capture without polling delay.

the vibration sensor price reflects a single fixed threshold once set, so applications needing to detect multiple distinct vibration intensity levels would need either software-based analog reading from a different sensor or multiple comparator-based modules tuned to different thresholds. Available at StemVolt, well-suited for makers building industrial machinery monitoring systems and practical threshold-based shock alert electronics projects.
