The SparkFun SEN-09199 is a vertical attachment of 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
