Keyestudio EASY plug Crash Sensor


Crash sensor, also known as snap-action switch, is an electric switch that is actuated by very little physical force.
It is a digital on-off input module necessary for elementary electronic.
By programming, it can be used for the light, sound device, key function of LCD display, 3D Printer position feedback, or other devices.
Note: this sensor needs to be used together with EASY plug control board.


  • Connector: Easy plug
  • Onboard status indicator LED
  • M3 mounting hole, convenient for fixation on other devices.
  • If collision happened, outputs LOW level signal; no collision, outputs HIGH level signal.

Technical Details

  • Dimensions: 44mm*20mm*18mm
  • Weight: 5.5g

Connect It Up

Connect the EASY Plug crash 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;// set pin for LED
int Shock=9// set pin for collision sensor
;int val;// set digital variable val
void setup()
pinMode(Led,OUTPUT);// set pin LED as output
pinMode(Shock,INPUT);// set collision sensor as input
void loop()
val=digitalRead(Shock);// read value on pin 9 and assign it to val
if(val==HIGH)// when collision sensor detects a signal, turn LED on.
} else

What You Should See

When an object crashes the metal switch of the sensor, the indicator LED is turned on. If no crash happened, LED is turned off.
