Product Description

The module is a capacitive touch switch module based on touch detection IC (TTP223B). Normally, the module output level is low, and the mode is low power mode. When the finger touches the corresponding position, the module will output high level, and the mode will change to fast mode; When there is no touch for 12 seconds, the mode switches back to low power mode. The module can be installed on the surface of non-metallic materials such as plastic and glass, and the thin paper (non-metal) is covered on the surface of the module, so long as the touch position is correct, it can be made into a button hidden in the wall, desktop and other places. This module allows you to avoid the annoyance of regular push-type buttons.

The module features are as follows:

Point type: the initial state is low, touch is high, do not touch is low (similar to the touch button function)

Low power consumption

The power supply ranges from 2 to 5.5V DC

Both front and back can be used as touch surfaces, which can replace the traditional touch keys
