Touch Sensor Kit Golden Digital Capacitive Switch Module for Arduino
Touch Sensor: Based on the touch sensor chip TTP223B£¬ the module is capacitive touch switch module. Normally it outputs low and it is at low power state. When you touch the appropriate location£¬ it will output high and switch to the quick response state. When not touched for 12 seconds£¬ it switches to low power state again. Touch Sensor (T): Based on a touch detection IC (TTP223-BA6)£¬ and the IC is in toggle mode; Power on£¬ the module output low level and the mode is low power mode; Touch related position with finger£¬ module will output contrast level ( ie£¬ the original output is high£¬ and then output is low after touch)£¬ and the mode is switched to fast mode and back to low-power mode 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: 1. Funny and easy to use£¬ can replace the traditional self-locking switch; 2. Increase the filter circuit£¬ the signal output stable; 3. Low power consumption; 4. Power supply can be 2~5.2V DC; 5. Immersion gold process£¬ long service life; 6. 4 x M2 screw mounting holes.
