Product Introduction
The TTP223 capacitive touch sensor module is a capacitive point-type touch switch module based on the touch detection IC (TTP223). In normal condition, this module outputs a low level, which is a low-power mode. When a finger touches the corresponding position, the module will output a high level. The module can be installed on non-metallic materials such as plastic and glass surfaces. In addition, a thin sheet of paper (non-metallic) is placed on the surface of the module. As long as the touching position is correct, it can be made into a button that is hidden in places like walls or tabletops. This module can help you avoid the trouble of regular pressing-type buttons.
Module Feature
- Operating voltage: 2.0V – 5.5V.
- Built-in status indicator light.
- The module has an automatic calibration function. When no key is touched, the system will re-calibrate. The re-calibration cycle is approximately 4.0 seconds.
- After power-on, there is a stable time of about 0.5 seconds required. During this period, do not touch the keys. At this time, all functions are prohibited.
- The module interface is a standard 2.54mm pin header for input and output connection. The connection via DuPont wires is very convenient.
- The PCB board has two fixed bolt holes, which can be fixed with screws.
TTP223 Touch Sensor Module Pin Functions
| Pin | Definition |
|---|---|
| VCC | Positive pole |
| GND | Power ground |
| OUT | Digital output |
- When the working voltage is between 2.5V and 5.5V, it defaults to the jog mode. When touched, it outputs a high level.
- Different working modes can be set through J1 and J2. It has installation holes and an LED status indicator (Effective when the output is at a high level).
| Touch Mode | Level Output | J2 | J1 |
|---|---|---|---|
| Jog mode | high level | No welding | No welding |
| Jog mode | low level | weld | No welding |
| Automatic Lock Mode | high level | No welding | weld |
| Automatic Lock Mode | low level | weld | weld |
Note: J2 sets the output level, and J1 sets the touch mode.
