About this product
A vibration switch module built on the SW-420 normally-closed vibration sensor. An LM393 comparator converts vibration into a clean digital 0 or 1 output, which suits alarms, tamper detection and simple knock or motion sensing with a microcontroller. The board includes bolt holes for fixed mounting.
