The module is a touch based detection of IC (TTP223B) of the capacitor typePoint moving typeTouch switch module. Under normal conditions, low level output module, pattern for the low power mode; when the fingers touch the corresponding position, the module will output high level, mode switching for fast mode; when the last 12 seconds not touched, mode and switch to low power mode. You can install the module in the non-metallic materials such as plastics, glass surface. In addition, the thin pieces of paper (non-metallic) covering on the surface of the module, as long as the correct location of the touch, can be made into a hidden buttons on the wall, desktop and other places. This module allows you to avoid the trouble of conventional pressing buttons.
Module features are as follows:
Point type: initial low touch is high, do not touch to a low level (similar to the touch key function)
low power consumption
The power supply can be 2~5.5V
Positive and negative can be used as a touch surface,Can replace the traditional touch key
4 M2 screw positioning holes, easy to install
With the optocoupler + bidirectional thyristor can touch the fluorescent lamp intelligent Home Furnishing project;
