TTP223B Digital touch Module

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 button.
 
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.
Power supply for 2 ~ 5.5V DC.
Response time (touch mode) : 60 mS
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
Size : 24 x 24 x 7.2 mm
