EASY plug Capacitive Touch Sensor



Are you tired of clicking mechanic button? Well, try our capacitive touch sensor. We can find touch sensors mostly on electronic device. So upgrade your Arduino project with our new version touch sensor and make it cool!!
This little sensor can "feel" people and metal touch and feedback a high/low voltage level. Even isolated by some cloth and paper, it can still feel the touch. Its sensitivity decrease as isolation layer gets thicker.
Note: this module needs to be used together with EASY plug control board.


  • Interface: Easy plug
  • Supply Voltage: 3.3V to 5V
  • Sensor type: Digital
  • Size: 45*20mm
  • Weight: 5g

Connection Diagram


Sample Code

int ledPin = 13;                // Connect LED on pin 13, or use the onboard one
int KEY = 12;                 // Connect Touch sensor on Digital Pin 12
void setup(){
 pinMode(ledPin, OUTPUT);      // Set ledPin to output mode
 pinMode(KEY, INPUT);       //Set touch sensor pin to input mode
void loop(){
  if(digitalRead(KEY)==HIGH) {      //Read Touch sensor signal
       digitalWrite(ledPin, HIGH);   // if Touch sensor is HIGH, then turn on
       digitalWrite(ledPin, LOW);    // if Touch sensor is LOW, then turn off the led
