TTP229 16 Channel Capacitive Touch Module
This is TTP229 16-Way Capacitive Touch Switch Digital Touch Sensor Keypad Module. 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 touchpads that make an ideal replacement for the old-fashioned keypads.
Capacitive touch allows electronics to sense when your finger is within a few millimeters of a surface to simulate a button “press” just like how the pushbutton works. Capacitive sensing may be used in any place where low to no force human touch sensing is desirable.

1. What is a capacitive touch module?
- The module is built around a capacitive touch switch module with a touch-sensing IC (TTP223B). The module output is low in normal operation, with low power consumption. When a finger touches the corresponding position, the module output is high; after 12 seconds, the module switches to low-power mode.
2. What does a capacitive touch sensor do?
- Capacitive sensing is a capacitive coupling-based technology that can detect and measure anything that is conductive or has a dielectric other than air. Based on electrical impulses in the human body, capacitive touch screens distinguish and sense specific touch locations, typically the fingertip.
3. How many types of capacitive touch sensors are there?
- Capacitive sensing is a capacitive coupling-based technology that can detect and measure anything that is conductive or has a dielectric other than air. Capacitive touch sensors are classified into two types: surface capacitive sensing and projected capacitive sensing. An insulator with a conductive coating on one side of its surface is used in surface capacitive sensing. A thin layer of an insulator is applied on top of the conductive coating.
4. How does a capacitive touch module work?
- A capacitive touch sensor functions similarly to a switch in that when contact, touch, or pressure is applied to its surface it opens an electrical circuit and allows currents to flow through it. Based on electrical impulses in the human body, capacitive touch screens distinguish and sense specific touch locations, typically the fingertip.
