SKU: SF-SEN-09197

A flexible piezo vibration sensor from Measurement Specialties, commonly used for detecting flex, touch, vibration, and shock. The PVDF polymer film generates a small AC voltage (up to ±90 V) when it moves, which can be brought down to ADC-readable levels with a simple resistor divider. This vers...

SKU: SF-SEN-09199

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...

SKU: DF-DFR0052

The DFRobot Vibration Sensor buffers a piezoelectric transducer that responds to strain changes by generating a measurable output voltage change which is propotional with the strength of vibration.So you can know the extent of vibration. Different from digital vibration sensor that only accounts...

SKU: AF-1767

A low-sensitivity, non-directional vibration switch that acts as a simple motion detector. Inside, a stiff spring is coiled around a central metal pin — when the switch is shaken or moved with enough force, the spring contacts the pin and closes the circuit. When still, the circuit remains open. ...
