Digital Capacitive Touch Sensor Switch Module for Rpi£¬Arduino£¬Mega260
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; Can be installed on various surfaces£¬ such as plastic£¬ glass and non-metallic materials. 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
