The Piezo Vibration Sensor Small Vertical 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 and forth. A simple resistor should get the voltage down to ADC levels. It can also be used for impact sensing or a flexible switch.
Voltage Sensitivity (open-circuit, baseline): 1.1 V/g.Flexible PVDF Piezo Polymer Film.
Wide dynamic range.
Laminated for higher voltage output.
Breadboard friendly leads.
Charge Sensitivity (baseline): 260 pC/g.
Resonance Frequency: 75 Hz.
Voltage Sensitivity (open-circuit, at resonance): 6 V/g.
Upper Limiting Frequency (+3 dB): 42 Hz.
