Description Grove-Piezo Vibration Sensor is suitable for measurements of flexibility, vibration, impact and touch. The module is based on PZT film sensor LDT0-028K. LDTM-028K is a vibration sensor where the sensing element comprises a cantilever beam loaded by an additional mass to offer high sensitivity at low frequencies. When the sensor moves back and forth, a certain voltage will be generated by the voltage comparator inside of it. A wide dynamic range ( 0.001H z~1000MHz) guarantees an excellent measuring performance. And, you can adjust its sensitivity by adjusting the on-board potentiometer with a screw.
