EASY plug Knock Sensor


The knock sensor is mainly composed of SW-280 vibration switch, which is an inductive proximity switch.
It is an electronic switch that transmits the sensing result to the circuit device and induces the circuit to start working when the vibration force is induced.
The module comes with a positioning hole for you to fix it to other devices.
You can make full use of it with creative thinking, like electronic drum, and so on.
Note: this module should be used together with EASY plug control board.


  • Connector: Easy plug
  • Working voltage: 5V
  • Sensor type: Digital

Technical Details

  • Dimensions: 38mm*20mm*18mm
  • Weight: 4.4g

Connect It Up

Connect the EASY Plug knock sensor to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.

Upload the Code

Copy and paste below code to Arduino IDE and upload.

int Led=13;//define LED interface
int Shock=8;//define knock sensor interface;
int val;//define digital variable val
void setup()
pinMode(Led,OUTPUT);//define LED as output 
pinMode(Shock,INPUT);//define knock sensor as output 
void loop()
val=digitalRead(Shock);//read the value of interface8 and assign it to val
if(val==HIGH)//when the knock sensor detect a signal, LED will flash.

What You Should See

Done uploading the code, if knock the sensor hard, the led will be turned on.
