Capacitive Touch Sensor Unit - Digital Output

Capacitive Touch Sensor Unit - Digital Output

Description:

The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module outputs low with low power consumption. When a finger touches the corresponding position, the module outputs high, if not being touched for 12 seconds, it switches to low-power mode.

Features:

* Plug and play
* Low power consumption
* Power supply for 2 ~ 5.5V DC

* Current: 3mA @ 5V
* Can replace the traditional touch button

Specification:

Test Code on UNO board:

const int SensorPin = 2;     // the number of the sensor pin

int SensorState = 0;         // variable for reading the sensor status

void setup() {
pinMode(SensorPin, INPUT);
Serial.begin(9600);
}

void loop(){
SensorState = digitalRead(SensorPin);
if (SensorState == HIGH) {
Serial.println(1);
}
else {
Serial.println(0);
}
}
