Here is the English version of the product description for the capacitive touch sensor:
It is a capacitive touch sensor module from the DevLab line, based on the TTP223B integrated circuit. Essentially, it is a device that transforms a simple touch into a precise digital signal, without the need for mechanical buttons or moving parts.
It was created to make it easy to integrate touch controls into electronic projects. Its electrode pad continuously monitors for changes in capacitance and outputs a clean HIGH logic signal when a touch is detected. It is ideal for quickly building modern control panels, interfaces for smart clothing (wearables), home automation switches, or touch lamps. It offers reliable, debounce-free detection with minimal wiring and almost zero power consumption in standby mode.
It stands out by featuring an internal auto-calibration and filtering circuit that eliminates noise and signal drift, ensuring highly reliable operation. Additionally, it is very versatile thanks to an onboard solder jumper that allows the user to easily choose between two operating modes: Momentary Mode (the output remains HIGH only while the sensor is being touched) and Toggle Mode (the output changes and holds its state with each new touch).
