- Power supply for 2 ~ 5.5V DC
- Operating Current(Vcc=3V): 1.5 – 3.0μA
- Operating Current(VDD=3V): 3.5 – 7.0μA
Description:
The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output is low, with low power consumption; When a finger touches the corresponding position, the module output is high, if not touched for 12 seconds, switches to low-power mode. The module can be installed in such surface plastic, glass, or 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 it hidden in the walls, desktops, and other parts of buttons.
Specification:
- Power supply for 2 ~ 5.5V DC
- Operating Current(Vcc=3V): 1.5 – 3.0μA
- Operating Current(VDD=3V): 3.5 – 7.0μA
- Response time: 60ms
Features:
- Low power consumption
- Can replace the traditional touch of a button
- Four M2 screws positioning holes for easy installation
Touch Sensor Interface:
- Control Interface: A total of three pins (GND, VCC, SIG), GND to the 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.
Package Included:
1 x TTP223-1 Based Capacitive Touch Sensor Module for Arduino
