The SW-420 Vibration Sensor Module is a sensitive and reliable shock and vibration detection module used to trigger alarms, motion detection, and security alerts. It operates based on a normally closed vibration switch that opens momentarily when a sudden vibration or movement is detected.
Equipped with an LM393 comparator circuit, this module outputs a digital HIGH/LOW signal corresponding to vibration activity. It features adjustable sensitivity, LED indicators, and a simple 3-pin interface compatible with Arduino, ESP32, Raspberry Pi, and STM32.
Compact, durable, and easy to integrate, it’s ideal for security systems, motion alarms, industrial machines, and DIY automation projects.
