a¦aЂ“a°a?a»a?a§a 1/2 aЂ~a©a?aµ 6 TTP223B  Digital Touch Sensor Capacitive Touch Switch Module DIY for Arduino Description: 100% brand new and high quality 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: Low power consumption Power supply for 2 ~ 5.5V DC Can replace the traditional touch of a button Four M2 screws positioning holes for easy  installation Specification: Item Min Typical Max Unit Power supply voltage VCC 2.0 3 5.5 V Output high VOH - 0.8VCC - V Output low VOL - - 0.3VCC V Output Pin Sink Current (@ VCC = 3V, VOL = 0.6V) - 8 - mA Output pin pull-up current (@ VCC = 3V, VOH = 2.4V) - 4 - mA Response time (low power mode) - - 220 mS Response time (touch mode) - - 60 mS Size 24x24x7.2 mm Touch Sensor Interface :(the last picture show) -Control Interface : A total of three pins (GND,  VCC, SIG), GND to ground , VCC is the power supply , SIG digital signal output  pin ; -Power Indicator : Green LED, power on the right that is shiny ; -Touch area : Similar to a fingerprint icon inside the area , you can touch the  trigger finger . -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 ;
