TTP223B Digital Touch Sensor Capacitive Touch Switch For Arduino
The module is a capacitive touch switch module based on touch detection IC (TTP223B). Under normal conditions, module output low level, mode is low power mode; When you touch the corresponding position with your finger, the module outputs high level, the mode switch for fast mode; When last 12 seconds without touching, mode switching to low power mode. You can install the module in the non-metallic materials such as plastics, glass surface.

The module allows you to dispense trouble of the usual press type buttons.
Features are as follows:
Point type: initial low level, touch is high, do not touch as low level (similar to the touch key function) Low power consumption 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
