This piezo sensor can be used for measurement of shock, vibration, flex and touch. When bent or moved the piezoelectric material produces a large AC voltage up to +/-90V at low current. Suitable for use with analogue to digital converters on microcontrollers when a resistor is used.

Impacts, vibrations and bending/flexing can be detected by this sensor. A voltage is created across piezoelectric materials when they are mechanically deformed. This voltage is AC because the deformation can happen in both directions. Although the voltage is a high +/-90V is can be read using an ADC (analogue to digital converter) in a microcontrollers.
The pins on the sensor fit into a standard breadboard for prototyping or can be soldered to.
