vibration and shock sensor acidity Languages such as Chinese andIntroduction: The vibration sensor is used for sensing the impact force, shocks and vibration. It has high vibration detection sensitivity while suppressing background sound signal which affect vibration sensors . It is consists of piezoelectric element, spring oscillator, Sensitivity adjustment knob, and led. We can regulate the knob to adjust the sensitivity. For example when adjusting the knob clockwise, the sensitivity increases led will light
