The Grove Piezo vibration sensor is suitable for measurements of flexibility Aten, vibrations, impacts and touch. The module is based on the pzt film sensor LDT 0-028. The sensor is moved back and forth, a certain voltage of the voltage comparator generates. A large frequency range (0.001 Hz ~ 1000 MHz) guarantees outstanding reading performance. And you can set the sensitivity by adjusting the potentiometer on the board with a screw.This text is machine translated.
