Are there any advantages of the product?
The knocking sensor is encapsulated in a glass shell, resulting in a simple and compact structure that is easy to install and integrate into various physical structures. The KY-031 can more sensitively capture small-amplitude vibrations or strike signals, providing real-time detection and quickly converting physical signals into electrical signals to meet the need for rapid response.

Instruction
Easy to install, it features mounting bolt holes and a digital LED; the LED flashes when the strike sensor detects a strike signal. Solder the sensor pins to the circuit according to the circuit diagram. Please test the sensor response before use to confirm its trigger sensitivity.

What should  I notice?
For purchasing electronic components, modules should have some basic knowledge of electronics. Most modules only provide descriptions or information. Beginners should be cautious.
