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 Aduino 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 decreases as isolation layer gets thicker.
  • Supply Voltage: 3.3V to 5V
  •  Interface: Digital

Sample Code:

int ledPin = 13; // Connect LED on pin 13, or use the onboard one

int KEY = 2; // Connect Touch sensor on Digital Pin 2

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
