The module is based on a touch sensing chip (TTP223BCapacitive touch switch module(Sensor Touch 2). In the normal state, the module output is low, the mode is in low power consumption; when the corresponding position is touched by the finger, the module outputs a high level, and the mode is switched to the fast response state.12When there is no touch, the mode is switched to low power consumption. The installation of the module in the non-metallic materials such as plastics, glass, acrylic plate surface, can be made into a hidden buttons on the wall, desktop and other places. This module allows you to avoid the trouble of traditional pressing keys.
Module features are as follows:
*Shen Jin Long quality life, to expand the touch area more intelligent
* The upgraded version increases the filter capacitor and the signal output is stable.
Point type: initial low touch is high, do not touch to a low level (similar to the touch key function)
Low power consumption,Easy to use
The power supply can be DC 2~5.5V
Can replace the traditional touch key
Touch when the output is high, does not touch the output low level
4 M2 screw positioning holes, easy to install
