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.

DFRobot Support — You can add hundreds of nodes and
because it is radio frequency module, the speed should be
close to the speed of light.

DFRobot Support — When you get error feedback, please
don't pay attention to that, you can keep the AT command
setting.
