Normally Open Vibration Sensor Module – Digital Output

The Normally Open Vibration Sensor Module is a compact digital sensor designed to detect subtle mechanical vibrations or movements. When no vibration is present, the module remains in an open (HIGH output) state. Upon detecting a vibration, the internal switch closes momentarily, sending a LOW signal to the output pin and illuminating the onboard green indicator LED.

This sensor is ideal for use in alarm systems, anti-theft devices, smart robotics, and motion-sensitive electronics. While the output can be read directly by a microcontroller’s digital pin, please note that the short duration of the vibration trigger may not be suitable for directly driving relays without intermediate signal conditioning or processing.
