Sparkfun Electronics Piezo Vibration Sensor - Large

This Piezo Vibration Sensor - Large 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. Flexible PVDF Piezo Polymer Film; Wide dynamic range; Laminated for higher voltage output; 0.1" breadboard friendly leads
