Piezo Vibration Sensor - Small Horizontal (Sparkfun SEN-09198)

The Minisense 100 from Measurement Specialties is a low-cost cantilever-type vibration sensor loaded by a mass to offer high sensitivity at low frequencies. Useful for detecting vibration and 'tap' inputs from a user. A small AC and large voltage (up to +/-90V) is created when the film moves back an forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact sensing or a flexible switch.

Comes with machine pins that allows for horizontal mounting.

We've seen this used as great musical inputs.
