Description
The SW-420 Vibration Sensor Module is a compact and sensitive module designed to detect vibration, movement, and tilt. When the module remains stable, its output stays high; when vibration or movement is detected, the sensor briefly changes state and provides a low digital output signal.
The module features an onboard LM393 comparator and indicator LED, making it easy to connect with Arduino and other microcontroller boards. Its adjustable sensitivity allows the detection level to be tuned according to the requirements of the project.
