TTP224 4-Way Capacitive Touch Switch Digital Touch Sensor Electronic Module For ArduinoItem NO.: TTP224-4

TTP224 4-Way Capacitive Touch Switch

Module application scope:

Widespread electronic consumer products, replacing traditional buttons, microcontroller learning, electronic competitions, product development, graduation design, and home industrial control application expansion, can be connected to our store's relay module to form a touch relay control switch, and connected to our store's buzzer module to form a touch alarm module.

Module Introduction Explanation:

1. This module uses FR4 PCB board with a thickness of 1.2mm, 0805 SMT components, 0603 red LED indicator light, and onboard TTP224 capacitive four key touch sensing IC

2. The interface of this module is a standard 2.54mm pin for input and output connections, and the DuPont cable connection is very convenient

3. The PCB size is 35 (mm) x 29 (mm), with 2 fixed bolt holes that can be locked with screws for fixation;

4. The module can set output mode, key output mode, maximum output time, and fast/low power consumption selection

Capacitive digital touch sensor switch hand touch detection module

Touch key detection IC, providing 4 touch keys. Touch detection IC is designed to replace traditional button keys with variable area keys. Low power consumption and wide operating voltage are the DC and AC characteristics of touch keys.

Working voltage 2.0V~5.5V

After powering on, a stable time of about 0.5 seconds is required. During this period, do not touch the keys,

At this point, all functions are disabled

Always perform self calibration

When the key is not touched, the recalibration cycle is approximately 4.0 seconds

Interface Description:

1. VCC: Connected to the positive pole of a 5V power supply

2. GND: Connect the negative pole of the power supply to the ground of the output trigger signal

3. OUT1-OUT4: Level output terminal

Output OUT can directly control the relay module of our store, as well as directly input the IO of the microcontroller or the IO of the ARDUINO development board
