Description
The vibration sensing system of this product composed of the buzzing and the contact spring, which has the characteristics of high sensitivity, high speed, and high performance. Piezoelectric ceramic spring hammer structure vibration signals detection, and through the LM358 OP-AMP and outputs the control signal, it is a low cost, high sensitivity, stable and reliable. Vibration detection can be controlled in a wider range, has been widely applied to automobiles, motorcycle anti-theft system, the vehicle alarm is 80% with this kind of sensor. The sensor can also be used with MCU, wireless transmitting module, wired alarm, etc. They are widely used in automobile anti-theft and other security products.
