Sparkfun - piezo vibration sensor - large mass sen-0919
This basic piezo sensor is often used for flex, touch, vibration and shock measurements. A small AC and large voltage (up to +/-90V) is created when the film moves back and 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 solderable crimp pins and a mass attached to the tip. This mass increases the sensitivity to motion.
* Flexible PVDF Piezo Polymer Film
* Laminated for higher voltage output
* 0.1" breadboard friendly leads
