Touch Sensor Module Kit w/ Direct and Toggle Mode for Arduino
Touch Sensor module: 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. Only when you touch the appropriate location£¬ it will output high. Touch Sensor (T) module: Based on a touch detection IC (TTP223-BA6)£¬ and the IC is in toggle mode; Power on£¬ the module output low level (You can modify the initial level by the toggle switch) and the mode is low power mode; Touch related position with finger£¬ module will output opposite level ( ie£¬ the original output is high£¬ and then output is low after touch). 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 or self-locking switch - Increase the filter circuit£¬ the signal output stable - Low power consumption - Working voltage: 2~5.2V DC
