EASY plug Capacitive Touch Sensor

Introduction

You can find touch sensors mostly on electronic device. Instead of buttons, upgrade your Arduino project with our new version touch sensor and make it cool!
The EASY Plug digital capacitive touch sensor provides a one-touch style switch on your Arduino project. It uses the most popular capacitive sensing technology which is the same as your mobile phone.
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. The sensitivity will decrease as the isolation getting thick.
Note: this module should be used together with EASY plug control board.

Features

Connector: Easy plug
Supply Voltage: 3.3V to 5V
Sensor type: Digital
Function range: 0℃ to 100℃

Technical Details

Dimensions: 45mm*20mm*18mm
Weight: 4.9g

Connect It Up

Connect the EASY Plug touch 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 ledPin = 13;// Connect LED on pin 13, or use a built-in led.
int KEY = 8;// 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 led on
}
else{
digitalWrite(ledPin, LOW);// if Touch sensor is LOW, then turn led off
}
}
