Compact Vertical Vibration Sensor for Taps and Motion Events

The Piezo Vibration Sensor Small Vertical is a compact cantilever-style vibration sensor for tap input, motion sensing, and low-frequency vibration detection.

This version mounts vertically and uses a small mass-loaded design to improve sensitivity at lower frequencies. It is a clean option when you need a small event sensor on a tight board layout.

Why you'll love it

• Compact sensor body: Easy to fit in small builds
• Vertical mounting style: Useful when board height and layout matter
• Mass-loaded cantilever design: Improves low-frequency sensitivity
• Good for tap and vibration events: Simple way to detect movement
• Passive two-pin output: Easy to pair with custom analog front ends

What you can build

Useful for tap inputs, alarm triggers, handheld gadgets, vibration logging, anti-tamper devices, and interactive builds that respond to knocks or motion.

Starter bundles

Add a resistor network, comparator or ADC input, and a microcontroller board for event capture or analog monitoring.

Recommended add-ons

Helpful extras include resistors, protection parts, breadboards, data loggers, and mounting hardware.

Technical specifications

Pinout & usage notes

This is a two-pin passive sensor with vertical leads for upright mounting. Use a protected analog input or comparator-based circuit.
