INTRODUCTION
This is an Arduino compatible piezo film vibration
sensor. It is made up of flexible piezo film and converter board. The sensor is
able to detect vibration, flexibility, impact and touch.
The film is a flexible component comprising a 28 µm thick piezoelectric PVDF
polymer film with screen-printed Ag-ink electrodes, laminated to a 0.125 mm
polyester substrate, and fitted with two crimped contacts. As the piezo film is
displaced from the mechanical neutral axis and bending creates very high strain
within the piezo polymer, high voltages (about ±90V) are generated. When the
assembly is deflected by direct contact, the device acts as a flexible
"switch", and the generated output is sufficient to trigger MOSFET or
CMOS stages directly.
The module uses universal Gravity 3Pin interface that is easy to plug and play.
It comes with Digital and Analog two output signals, which is suitable
for all kinds of different applications. The piezo vibration sensor is not only
able to detect strong shocks, but also to detect slight vibrations. There is an
on-board sensitivity adjustment potentiometer, you can adjust it to
increase/decrease the output threshold value.
Meanwhile, the piezo film sensor has a wide dynamic range (0.001Hz~1000MHz)
also guarantees an excellent measuring performance.
