SW-420 NC Type Vibration Sensor Module Vibration Switch for Arduino Smart Car

 When the module is not vibrating, the vibration switch has been set to low output state output, the green indicator light is closed. 
 The product vibrates, vibration switches momentary disconnect, output high drove, the green light does not light up. 
 The output can be connected directly to the microcontroller, which detects the high and low levels, so as to detect whether the environment emitted the vibration, play a role in the alarm. 


  • Use SW-420 normally closed vibration sensor 
  • comparator output,  clean  signal, good waveform, strong driving ability,> 15mA
  • Operating  voltage 3.3V ~ 5V 
  • Output format: Digital switching output (0 and 1) 
  • With a wide voltage LM393 comparator 
  • With screw holes for easy installation 
  • Small size PCB: 3.2 x 1.4cm 


  •  current direction cannot be reversed, otherwise, it is possible to burn the chip 
  •  signal LED light output low, signal LED OFF output is high 
  •  The output level close to the input voltage 


 Various oscillations trigger: Arduino, Smart, earthquake alarm, motorcycle alarm, Anti-theft alarm 

Arduino Hook up with SW-420

Connect Vcc pin of sensor board to 5V pin of Arduino board, connect GND pin to GND pin of Arduino, Connect DO output signal pin of sensor board to Arduino digital pin D3. Do some calibration and adjust the sensitivity threshold, then upload the following sketch to the Arduino board.

Arduino Code for Logic State Output from the sensor module, here onboard LED of Arduino indicates the presence of vibration.
