Are you tired of clicking a mechanic button? Try our capacitive touch sensor. Right now we can find touch sensors in most 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 still can feel the touch. And the sensitivity will decrease as isolation get thicker.

Improvement List

  • Wide voltage range from 3.3V to 5V
  • Standard assembling structure (two 3mm holes with multiple of 5cm as interval)
  • Icons to simply illustrate sensor function
  • High-quality connector
  • Immersion gold surface


  • Supply Voltage: 3.3V to 5V
  • Interface: Digital
  • Size:22x30mm

Connection Diagram


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
