TTP223B Capacitive Touch Switch Module, 2-5V, for Arduino

This is Based on the touch sensor chip TTP223B ( Direct Mode ), the module is a capacitive touch switch module; Low output and low power; When you touch the appropriate part, it will output high and switch to the quick response state; It will switches to low power state again if not touch for 12s. If the module is mounted in the surfaces of non-metallic materials, such as plastic, glass, acrylic, you can make the keys hidden in the walls and desks. Features Funny and easy to use, can replace the traditional button; Increase the filter circuit, the signal output stable; Low power consumption; Power supply can be 2~5V DC; Immersion gold process, long service life; 4 x M2 screw mounting holes Applitations Wide.
