This capacitive touch sensor module uses the TTP229 integrated circuit, making it easy to add capacitive touch input to your project. It features 16 sensitive touch pads that make an ideal replacement for the old fashioned keypads.Specifications:
-On-board 16-key TTP229 capacitive touch sensor IC -On-board power indicator LED -Working Voltage Range: 2.4 V to 5.5 V -Configurable output mode -PCB Size: 49.3 x 64.5 mm -
- The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output low, low power consumption; When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode.
- Jog type : the initial state is low , high touch , do not touch is low ( similar touch of a button feature )
- Module can be installed in such as surface plastic, glass of non-metallic materials
- 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 buttonsFeatures:
- Low power consumption
- Power supply for 2 ~ 5.5V DC
- Can replace the traditional touch of a button
- Four M2 screws positioning holes for easy installation
