Are there any advantages of the product?
This spring sensor module is made of excellent metal and PCB, featuring low power consumption and stable operating voltage. The SW-18015P vibration sensor uses a mechanical spring structure, offering high sensitivity and omnidirectional operation, triggering at any angle. It provides a reliable vibration response for low-current circuits, making it suitable for simple vibration alarms or detection.

How to use it?
Installation is convenient, with mounting bolt holes. Simply solder the sensor pins to the circuit according to the circuit diagram. The switch is normally in the open state, temporarily closing when sufficient vibration or tilt is detected. 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.
