SW-420 Vibration Sensor Module for Arduino

The SW-420 vibration sensor module is a simple shock and vibration detector for Arduino projects that lets your circuit sense tapping, movement, impact, or machine vibration and trigger an immediate response. Built for motion-sensitive prototypes, it is ideal for alarms, anti-tamper devices, robotics, and equipment monitoring where you need quick vibration detection rather than precise measurement. This SW-420 module is easy to integrate with Arduino and other microcontroller platforms using a basic signal connection, making it a practical choice for DIY automation, interactive builds, and rapid prototyping.
