TTP223B Digital Touch Sensor Capacitive Touch Switch Module For Arduino

The description The module is based on the capacitive touch switching module IC (TTP223B). In the normal state, the unit output is low, and the power consumption is low. When the finger touches the corresponding position, the module output is high, if not touched for 12 seconds, switch to the low power mode. Jog type: initial state low, touch high, do not touch low (similar touch of button). The unit can be installed in the surface such as plastic, glass of non-metallic materials. In addition to a thin sheet (non-metallic) covering the module surface, as long as the correct location to touch, you can make hidden in the walls, desktops and other parts of the buttons. Features 1. Low power consumption 2. Power supply for 2~5.5V DC 3. It can replace the traditional touch of a button 4. Four M2 screws positioning holes for easy installation
