TTP223 Érintőérzékelő modul YFRobot Érintőkapcsoló Érintőkapcsoló érzékelő
TTP223 Touch Sensor Module YFRobot Touch Switch Touch Switch Sensor
Description
The module is based on a touch-sensing IC  (TTP223B) capacitive touch switch module. In the normal state, the module output  low, low power consumption; When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode.
Jog type: the initial state is low, high  touch, do not touch is low ( similar touch of a button feature ).
Module can be installed in such as surface  plastic, glass of non-metallic materials.
In addition to the thin paper ( non-metallic )  covering the surface of the module, as long as the correct location of the  touch, you can make hidden in the walls, desktops and other parts of buttons.
Features
1. Low power consumption
2. Power supply for 2 ~ 5.5V DC
3. Can replace the traditional touch of a button
4. Four M2 screws positioning holes for easy  installation

Touch Sensor Interface
1. Control Interface: A total of three pins (GND,  VCC, SIG), GND to ground, VCC is the power supply, SIG digital signal output pin;
2. Power Indicator: Green LED, power on the right that is shiny;
3. Touch area: Similar to a fingerprint icon inside the area, you can touch the trigger finger.
4. Positioning holes: 4 M2 screws positioning hole diameter is 2.2mm, the positioning of the module is easy to install, to achieve inter-module combination.
