The module is based on a touch-sensing IC TTP223 capacitive touch switch module.
Trigger setting mode:(1- Greater than Short;0- Greater than No Short)
Power supply: 2.5v-5.5v/2W
Use effect: AB = 00: no lock high TTL level output; AB = 01: self-locking high TTL level output; AB = 10: no lock low TTL level output; AB = 11: self-locking low TTL level output
Touch key switch module stable touching detection of human body for replacing traditional direct switch key.
A very useful addition for projects or applications where a conventional mechanical button or switch is not a perfect choice.
The touch button capacitive switches module can be installed in plastic, glass surface non-metallic materials. As long as the touch of the correct position, you can make hidden in the wall, desk and other places.
