Main Features:
● Grove piezo vibration sensor is suitable for measurements of flexibility， vibration， impact and touch.
● The module is based on PZT film sensor LDT0-028. When the sensor moves back and forth， a certain voltage will be created by the voltage comparator.
● It has a high receptivity for strong impacts， a wide dynamic range ( 0.001Hz - 1000MHz ) also guarantees an excellent measuring performance.
● You can adjust its sensitivity by adjusting the potentiometer with a screw.
● Applications: Vibration sensing in washing machine; low power wake-up switch; low cost vibration sensing; car alarms; body movement; security systems.
