Digital Capacitive Touch Sensor Switch Module for Arduino - Blue + Golden
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; 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
