Module touch sensor sentuh TTP223 TTP223B TTP BLUE Arduino_uno wemos

PRODUCT 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: 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: 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 .
