What is a TTP223 1-Channel Capacitive Touch Sensor Module?

The TTP223 is a high-sensitivity, low-power capacitive touch switch module. Instead of mechanical buttons, it detects human touch through an electrode plate. When your finger touches the module’s sensing area, it triggers an output signal (digital HIGH or LOW), making it perfect for replacing traditional push buttons in your circuits.

This particular module comes in a compact red-colored PCB version, making it not just functional but also visually appealing for your project builds.

Types of Touch Modes

The TTP223 module can be configured internally to operate in different modes based on your project needs:

  1. Momentary Mode (Default):

    • Output remains HIGH as long as you are touching the sensor.

    • Ideal for replacing buttons in user interfaces.

  2. Toggle Mode (Configurable):

    • A touch switches the output state: ON on first touch, OFF on second touch.

    • Great for making touch-activated lamps, appliances, etc.

(Mode configuration involves modifying the onboard A and B solder pads.)

Pinout Description

Pin Function
VCC Power supply (2V – 5.5V DC)
GND Ground
I/O Output pin (Digital signal)

Connect the VCC and GND to your power source, and read the I/O pin with a microcontroller like Arduino, ESP32, or Raspberry Pi.

Real-World Applications of TTP223 Capacitive Touch Sensor

The TTP223 module is incredibly versatile and can be used in various innovative applications:

  • Touch-Activated Lights: Create lamps that switch ON/OFF with just a touch.

  • Hidden Switches: Place the module under non-metallic surfaces for invisible touch controls.

  • Home Automation: Integrate into smart home projects for intuitive device control.

  • Wearable Electronics: Lightweight enough for wearables like smart badges or interactive clothing.

  • Musical Instruments: Trigger notes or effects with touch in DIY musical setups.

  • Interactive Art Installations: Use touch sensors to create responsive artwork or displays.
