The SW-420 Motion/Vibration Sensor Module is a sensitive and reliable device designed for detecting motion or vibration events. It is ideal for use in theft alarms, earthquake warning systems, smart vehicles, or any system that needs to respond to physical movement or vibration.
This module uses a normally closed vibration sensor (SW-420) and an LM393 comparator to provide a clean, digital output (0 or 1) that can be directly read by a microcontroller like Arduino, ESP32, or Raspberry Pi. When the sensor is idle (no vibration), the output is LOW and the onboard LED is ON. When vibration is detected, the output jumps to HIGH and the LED turns OFF.
