Description
TTP223 capacitive touch digital sensor. The TTP223 is a touchpad detector IC with 1 touch key. The TTP223 detection IC is designed to replace traditional buttons. Low power consumption
and wide working voltage are the most important features for DC or AC application.
TTP223 capacitive touch digital sensor specifications:
– Works on 2.0-5.5V
– Dimensions: 29 * 16 mm

Arduino code example:
const int TouchPin=9;
const int ledPin=12;
void setup() {
pinMode(TouchPin, INPUT);
pinMode(ledPin,OUTPUT);
}
void loop() {
int sensorValue = digitalRead(TouchPin);
if(sensorValue==1)
{
digitalWrite(ledPin,HIGH);
}
else
{
digitalWrite(ledPin,LOW);
}
}

This is another product that exceeds my expectations. Tested in combination with this housing: http://www.hobbyelectronica.nl/product/behuizing-86-arduino-lcd/ This sensor is placed on the inside against the plastic wall of the housing and responded fine by placing my finger on the outside above the sensor. Can also be used as a capacitive proximity switch to detect objects. I find the sensitivity to be set just right by the manufacturer. You can't set it yourself. You could experiment by increasing the distance between the sensor and your finger by bits, by placing a plastic layer between them. An indication an indicator LED lights up when your finger comes close. Responds to both the top and bottom of the circuit board.
