10 Pack TTP223B Digital Touch Capacitive Sensor Switch Module DIY for Arduino Raspberry Pi #adAiTrip #ad
- This module is capacitive type jog mode touch switch module that is based on a touch detection IC TTP223B. Feature：ttp223b chip, low power consumption, sig; both positive and negative can be used as a touch surface, and power supply is DC 2-5.
5v; green led indicator, and it is bright when power on right; Control port: GND, VCC, and replace the traditional touch of a button.
You can put to a thin paper non-metallic cover the surface of the module, that you can put it hidden in the walls, when touch the correct location of the module, desktops and other buttons.
In the normal state, low power consumption, but when a finger touches the corresponding position, the module output high, the module output low, if not touched for 12 seconds, switch to low-power mode. Module can be installed in such as surface plastic, glass of non-metallic materials. Allows you to remove the worry of conventional push-type keys.
