PROXIMITY-TOUCH-CT-REF

非接触式按键参考设计使用瑞萨电子的电容式触摸解决方案，可以检测手指和手在接近，无需物理接触。 电极通过自电容检测手指的接近程度，并打开 LED。 该演示解决方案与所有类型的瑞萨电子电容式触摸 CPU 板兼容。

瑞萨电子的非接触式按键参考设计解决了传统技术（红外传感器、超声波等）的问题。With Renesas' touchless button design, all you need is an electrode; it is not affected by light, and it can be combined with other capacitive functions.

The design should be used for the following use cases:

• When you don't want to or cannot touch a surface (elevator buttons, etc.)
• When your hands are occupied (vending machines, etc.)
• When your hands are wet (refrigerators)
• Other items that you don't want to touch (smart toilets)
