TTP223 Capacitive Touch Sensor Module – 1 Channel | Compoden
TTP223 1 Channel Capacitive Touch Sensor Module
The TTP223 is a 1-channel capacitive touch sensor module that detects human touch through a metal surface, glass, or plastic. It uses the TTP223B IC, providing a stable digital output when a touch is detected. Ideal for replacing mechanical buttons in interactive projects.

Compatibility
Works with 3.3V and 5V systems like Arduino Uno, Nano, ESP32, ESP8266, and Raspberry Pi Pico. The module outputs a clean 0-3.3V or 0-5V signal depending on supply voltage. Common pairings include any microcontroller with a digital input pin.
Wiring Notes
Connect VCC to 3.3V or 5V, GND to ground, and OUT to a digital pin. Keep wires short to avoid false triggers. Set the output mode using the jumper: A for momentary (high while touched), B for toggle (output state changes on each touch). No external components needed.
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?
Yes, it works with any Arduino board. Connect OUT to a digital pin and read HIGH when a touch is detected.
How does the toggle mode work?
In toggle mode (jumper on B), each touch toggles the output state; it stays high after the first touch, then goes low on the next, acting like a latching switch.
Can it detect touch through thick glass?
It can detect through up to 3mm of glass or plastic. Sensitivity may vary with material thickness and surface area.
