SW-420 Normally Closed Vibration Sensor Module
SW-420 normally closed vibration sensor module with adjustable sensitivity—ideal for alarms, anti-theft systems, and vibration detection projects.
Description
The SW-420 Normally Closed Vibration Sensor Module is a compact and reliable sensor designed to detect vibrations or shocks in its environment. It features the SW-420 vibration switch, which operates in a normally closed (NC) configuration, providing a digital output signal whenever vibration exceeds a preset threshold.
The module includes a sensitivity adjustment potentiometer, allowing you to fine-tune its response for different applications. It is fully compatible with popular microcontrollers such as Arduino, ESP32, ESP8266, Raspberry Pi, and STM32, making integration into DIY and embedded projects straightforward.
Common applications include alarm systems, anti-theft devices, earthquake detection, robotics, and vibration monitoring in machinery or equipment. Its small form factor, low cost, and easy interfacing make it ideal for both beginners and advanced users.
