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 solder pins that allows for vertical mounting.
Features:
* Flexible PVDF Piezo Polymer Film
* Wide dynamic range
* Laminated for higher voltage output
* Breadboard friendly leads
