Capacitive Touch Sensor

The Digital Sensor TTP223B Module Capacitive Touch Switch is based on a touch-sensing IC (TTP223B) capacitive touch switch module.

Touch Sensor Interface :

1. Control Interface: A total of three pins (GND, VCC, SIG), GND to the 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.

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
5. Output Pin Sink Current (@ VCC = 3V, VOL = 0.6V) : 8 mA
6. Output pin pull-up current (@ VCC = 3V, VOH = 2.4V) : 4 mA
