The vibration sensor uses a piezoelectric element to measure vibration on a surface and connects to an analog input.
This sensor buffers a piezoelectric transducer. As the transducer is displaced from the mechanical neutral axis, bending creates strain within the piezoelectric element and generates voltages.
If the assembly is supported by its mounting points and left to vibrate “in free space” the device will behave as a form of vibration sensor. The sensing element should not be treated as a flexible switch, and is not intended to be bent.
