Lead Description:
1. The blue line is the signal output through the 358 op amp output, high level when there is no vibration, and when there is vibration
low level
2. Red line power supply: +12V
3. The black wire is the ground wire
Functional principle:
This product adopts a vibration sensing system composed of buzzer and contact spring, which has the characteristics of high sensitivity, fast speed and high performance. The vibration signal is detected by the piezoelectric ceramic sheet and the spring weight structure inside, and the control signal is amplified and output by an operational amplifier such as LM358. It has the advantages of low cost, high sensitivity, stable and reliable operation, and a large adjustable range of vibration detection. It is widely used. In the anti-theft system of automobiles and motorcycles, 80% of the vehicle alarms currently use this type of sensor. The interior of the sensor adopts SMT patch technology and is assembled with imported components. It is widely used in automobile anti-theft and other security products, and has become the low-cost and practical first-choice product in modern security.
