Description:
The TTP223 Touch Sensor 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, it switches to low-power mode.
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
- It 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 TOUCH SENSOR
