SW-420 Vibration Sensor Module | DC 3V–5V Normally Closed Shake Sensor for Arduino, Alarms, DIY Projects (Blue)

Product Description

The SW-420 Vibration Sensor Module is a low-cost, plug-and-play shock detection sensor that triggers an output when physical vibration or movement is detected. Operating on 3V to 5V, it's ideal for Arduino, ESP32/ESP8266, Raspberry Pi, and microcontroller projects. With a normally closed (NC) configuration, this sensor is widely used in theft alarms, vibration-activated lights, and smart monitoring systems.
