The Piezoelectric Tap Shock and Vibration Sensor Module uses a metal ceramic piezo disc to detect shock and vibration, providing both TTL level and analog signal output, operating from 5V DC with up to 1A maximum control current and an onboard LED indicator. The piezoelectric shock tap sensor works because piezoelectric materials generate a small electrical voltage whenever they’re mechanically stressed — struck, tapped, flexed, or vibrated — and this module amplifies that tiny signal into a usable electronic output.
The vibration sensor piezoelectric’s TTL output gives a clean digital trigger signal useful for simple tap-detection or impact-alarm applications, while the analog output reflects relative vibration or impact intensity for applications needing graduated shock-level data rather than a simple binary trigger. Notably, this vibration sensor module’s 1A maximum control current rating suggests it can directly switch a small load like an LED, buzzer, or relay coil, going beyond simple signal output that most sensor modules provide to a microcontroller.
As a piezoelectric shock sensor, the piezo disc generates output proportional to mechanical stress regardless of cause, so it cannot distinguish an intentional tap from incidental vibration like nearby foot traffic, requiring careful mounting and possibly software filtering for accurate tap-only detection. A practical choice for builders and enthusiasts, this sensor module available at StemVolt.
