TTP223 Capacitive Touch Sensor Red

TTP223 Capacitive Touch Sensor Red

The TTP223 capacitive touch sensor red is a reliable touch input module. It works through plastic, glass, or wood up to 3mm thick. This sensor is ideal for Arduino, ESP8266, and Raspberry Pi projects. It offers low power consumption and adjustable sensitivity.

This touch sensor outputs a digital HIGH signal when touched. It runs on 2.0V to 5.5V, making it compatible with 3.3V and 5V systems. The onboard potentiometer lets you fine-tune the trigger capacitance. Use it to replace mechanical buttons in your designs.

The TTP223 capacitive touch sensor red detects human touch through non-conductive materials. It uses capacitance changes to register a touch event. This makes it perfect for sealed or waterproof enclosures. The sensor can trigger actions like turning on lights or sending data. It responds instantly with no moving parts. This reduces wear and tear over time. The module is small and easy to mount. It works with common microcontrollers without extra components. You can adjust sensitivity to avoid false triggers. This flexibility makes it a top choice for many projects.
