The TTP223B module is a miniature and highly efficient digital capacitive touch sensor. It detects a light touch to the metal sensor pad through a change in electrical capacitance, without requiring mechanical pressure. The module operates with a wide range of supply voltages (typically 2V to 5.5V), consumes minimal energy, and provides a clear digital output signal (HIGH/LOW). It can be configured in two modes: "Button" (the signal is active only while touching) or "Toggle" (each touch toggles the output state). With its micro-design, easy connection (VCC, GND, SIG/OUT), and high noise immunity, the TTP223B is ideal for adding a modern touch interface to projects with Arduino, ESP, and other microcontrollers, as well as for directly replacing mechanical buttons in devices.



The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output low, low power consumption; When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode.

 

Features:
Low power consumption
Power supply for 2 ~ 5.5V DC
Can replace the traditional touch of a button
Four M2 screws positioning holes for easy installation
