RED TTP223 Capacitive Touch Sensor Module – 1 Channel Touch Switch
RED TTP223 1 Channel Capacitive Touch Sensor Module
The RED TTP223 module is a compact single-channel capacitive touch sensor built around the TTP223-BA6 IC. It detects a finger touch on its sensing pad and toggles the output accordingly, requiring no physical pressure. The module handles the capacitive sensing, debounce, and output drive, making it easy to add touch input to Arduino, ESP32, or Raspberry Pi projects.

What You Can Build With This
- Touch-controlled LED lamp – toggle on/off with a tap
- Capacitive secret switch hidden under a non-metal surface
- Arduino-based door lock activated by touch pattern
- Proximity-based interactive art installation using the sensor's field
Compatibility
The TTP223 module works directly with any 3.3V or 5V microcontroller board, including Arduino Uno, Nano, ESP8266, ESP32, Raspberry Pi Pico, and STM32. Its digital output drives a GPIO pin directly. It pairs well with relays, motor drivers, or LED strips for adding touch control without a mechanical switch.
Wiring Notes
Connect VCC to 3.3V or 5V, GND to ground, and OUT to a digital input pin. The on-board LED indicates touch. A jumper on the rear selects between momentary (touch-hold) and toggle (touch-latch) output modes. Keep the sensing area free of conductive paths; thin non-conductive overlays like acrylic or tape can hide the pad.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Nano?
Yes, wire VCC to 5V, GND to GND, and OUT to any digital pin like D2. The module's logic high matches Arduino's 5V level.
Can I adjust sensitivity?
The onboard capacitor sets baseline sensitivity. You can replace it with a 0–50pF capacitor to change the touch distance, but the module doesn't include a trim pot.
Does it work through glass or plastic?
Yes, the capacitive field passes through insulating materials up to 2–3 mm thick. Mount the pad behind a non-conductive panel for a hidden touch button.
