TTP223 Capacitive Touch Sensor Module

The TTP223 Capacitive Touch Sensor Module is an efficient and user-friendly replacement for traditional mechanical push buttons. Using capacitive sensing technology, it detects a human finger touch and sends a digital signal (HIGH or LOW) to your microcontroller or electronics system. Compact, low-power, and highly sensitive, it is ideal for Arduino (https://electroway.org/product-category/arduino-and-accessories/arduino-boards/), Raspberry Pi (https://electroway.org/product-category/electronic-accessories/mounts-and-cases/raspberry-pi-mounts-and-cases/), NodeMCU (https://electroway.org/product-category/iot-and-smart-solutions/iot-modules/nodemcu/), and other embedded projects.
