The TTP223 single-channel capacitive touch sensor module is a small touch-switch board that replaces a mechanical push button with a simple finger touch. It detects a touch on its pad and gives a clean digital output signal, making it a favourite building block for makers, students, and anyone working on home-automation, smart-garden, or DIY electronics projects.
Key features
- Based on the popular TTP223 capacitive touch IC.
- Single channel – one touch pad per module for straightforward wiring.
- Digital output that reads easily as HIGH/LOW on a microcontroller pin.
- Compact board that fits neatly into breadboards and small enclosures.
- Commonly compatible with Arduino, ESP8266/ESP32, Raspberry Pi, and similar boards.
Typical uses
- Touch-activated switches for lamps, fans, and small appliances.
- Trigger inputs for irrigation timers and smart-garden controllers.
- Hidden touch buttons behind plastic, glass, or acrylic panels.
- Learning and prototyping in electronics courses and hobby projects.
How to choose / tips
- Confirm your controller's logic voltage matches the module before wiring.
- Mount the touch pad close to the surface you want to tap for best response.
- Order a couple of spares if your project uses several touch points.
