Piezo Vibration Sensor - Large

This essential piezo sensor from Measurement Specialties is great for flex, touch, vibration, and shock measurements. When the film moves back and forth, it generates a small AC and a large voltage (up to +/-90V). A simple resistor can bring the voltage down to ADC levels. It can also be used for impact sensing or as a flexible switch. It comes with solderable crimp pins. Key features include a flexible PVDF Piezo Polymer Film, a wide dynamic range, lamination for higher voltage output, and 0.1' breadboard - friendly leads. Available documents are the datasheet (LDT0 - 028K) and the technical manual.

Using this piezo vibration sensor is easy. First, connect it to your circuit using the solderable crimp pins. For measurements, just place it where you want to detect flex, touch, vibration, or shock. When the film starts moving, it will generate a voltage. To make the voltage suitable for your ADC, use a simple resistor. As an impact sensor or flexible switch, position it in a place where it can receive the impact or be triggered easily. When handling this sensor, be gentle as the piezo polymer film is flexible and can be damaged if bent too hard. Keep it away from extreme temperatures and humidity. To maintain it, just keep it clean and free from dust. Check the connections regularly to make sure they are secure.
