1. Onboard TTP223 capacitive-touch touch sensor IC;

2. The onboard level status indicator;

3. Operating voltage: 2.0~5.5V;

4. PCB board size: 29 (mm) x 16 (mm);

Capacitive touch sensor switch digital hand touch detection module;

Touch key detection IC, provides a touch button. Touch detection IC is designed to replace traditional keys with a variable area;

Button key design. Low power consumption and wide operating voltage are the contact key features of DC and AC;

Operating voltage 2.0~5.5V;

After power-up time of about 0.5sec require stable, and this time period do not touch the key pad;

At this time all functions are disabled;

Always self-calibration;

When the key is not to be touched, re-calibration period is about 4.0sec.

Application:

A wide range of consumer products;

Waterproof electrical appliances;

Button key replacement.

Board with blue LED.

Board size: 15.5 x 23.5 mm.

1 foot power supply + VCC;

2 feet for the output OUT;

3 feet for the power supply - GND;

OUT output can directly control our shop relay module can directly enter the microcontroller development board IO IO or ARDUINO

Module output mode can be selected. (Short-circuit board with solder pads A or B, you can change the output mode, short circuit is 1, OFF = 0).
