Digital Capacitive Touch Switch Module is based on TTP223B. Normally, the output is low and keeps at a low power state. When a touch is sensed on the circular marked region, it outputs high and switches to the quick response state. When not being touched for 12 seconds, it switches to a low power state again. If the module is mounted in the surfaces of non-metallic materials such as plastic, glass, acrylic, you can make the keys hidden in the walls and desks
1 Channel Capacitive Touch Sensor Module uses the touch-sensing IC TTP223 to sense the touch input thus making it easy to add capacitive touch input to your project. The touching detection IC is designed for replacing traditional direct button keys with diverse pad sizes. The module has a single touchpad. Power the module with 2 ~ 5.5V DC and the touchpad is all active to sense the input. The single Channel Capacitive Touch Sensor Module is easy to interface with. It can be used along with a microcontroller or an Arduino or even without one. When a capacitive load (such as a human hand) is in close proximity to the sense-pad, the sensor detects the change in capacitance and activates the switch. Custom sense-pads can be made from nearly any conductive material and these sensors can detect touch through thin layers of non-conductive materials such as glass, plastic, fabric, or even wood. 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, switch to low-power mode. In addition to the thin paper ( non-metallic ) covering the surface of the module, as long as the correct location of the touch, you can make hidden in the walls, desktops, and other parts of buttons.
Touch Sensor Interface
- Control Interface: A total of three pins (GND, VCC, SIG), GND to 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 2mm, the positioning of the module is easy to install, to achieve inter-module combination
