1, onboard TTP223 capacitive touch induction IC
2,onboard level indicator
3, working voltage: 2.0V-5.5V
4, PCB board size: 29 (mm) x16 (mm)
Capacitive digital touch sensor switch module
Touch key detection IC, providing 1 touch key. The touch detection IC is use to the variable area bond to replace the traditional to design. Low power consumption and wide operating voltage is DC and AC features of touch keys.
Working voltage 2.0V~5.5V
Need stability time of about 0.5sec after power up, not in this period of time the key is used in touch, then all functions are prohibited. Always perform a self calibration. When the key is not touched, re calibration cycle is about 4.0sec
Application
Extensive consumer products
The waterproof appliance
The button key substitution
Equipped with blue LED indicator
Board size: 15.5 X 23.5 mm
1 PIN is the supply + VCC
2 PIN is the output OUT
3 PIN is the power supply - GND
Output OUT directly control relay module, also directly enter the MCU IO or ARDUINO development board, IO module Output mode can choose. (the tin short circuit board A or B pad, which can change the output mode, short circuit 1, off 0)
