KeyeStudio EASY PLUG RJ11 Capacitive Touch Sensor Module - Digital Touch Input for Arduino Projects

The KeyeStudio EASY PLUG RJ11 Capacitive Touch Sensor Module provides a digital touch input for Arduino projects, replacing a mechanical button with a touch-sensitive surface. It can detect human touch and metal contact, and the current listing notes that it may still respond through thin cloth or paper with reduced sensitivity.

The module uses the EASY PLUG connector for tidy wiring to compatible control boards. It is useful for touch lamps, interactive panels, smart devices, and user-interface demos, especially when paired with the RGB Full Color LED Module or relay outputs.

Capacitive sensing depends on grounding, panel material, moisture, and nearby metal. Test sensitivity after final enclosure assembly before relying on the input.

  • Panel Note - Thin paper or cloth may still allow sensing.
  • Noise Note - Avoid nearby high-current wires.

Application Scenarios

1. Arduino Digital Input Test

Read the touch sensor output and print its state.

const int sensorPin = 2;

void setup() {
  Serial.begin(115200);
  pinMode(sensorPin, INPUT);
}

void loop() {
  Serial.println(digitalRead(sensorPin));
  delay(100);
}

2. LED Event Indicator

Turn on an LED when the module output is touched.

const int sensorPin = 2;
const int ledPin = 13;

void setup() {
  pinMode(sensorPin, INPUT);
  pinMode(ledPin, OUTPUT);
}

void loop() {
  digitalWrite(ledPin, digitalRead(sensorPin));
}

3. MicroPython GPIO Monitor

Monitor the digital signal from a Pico-style board.

from machine import Pin
import time

sensor = Pin(15, Pin.IN)

while True:
    print(sensor.value())
    time.sleep(0.1)
