The TTP223B is a digital capacitive touch sensor module that uses the TTP223B IC (Integrated Circuit). It is a single-channel touch sensor that detects a human touch on its surface. It can be used as a touch switch to trigger an event or action, such as turning on a light or activating a motor. The TTP223B is a low power consumption module and can operate at 2.4V~5.5V. It is easy to use, and its output can be read directly through its digital output pin. It can be connected to any microcontroller or microprocessor, including Raspberry Pi, ESP8266 and others. This module has a small size and is easy to install, it can be used in many applications such as DIY projects, home automation and industrial control.
