描述

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。借助瑞萨电子的非接触式按钮设计,您只需要一个电极;不受光影响,并且可与其他电容功能结合使用。

该设计可应用于以下用例:

  • 当您不想或不能触摸表面(比如电梯按钮等)时
  • 当你的手被占用时(比如自动售货机等)
  • 当你的手湿时(比如冰箱)
  • 其他你不想碰的物品(比如智能马桶)

特性

  • 基于瑞萨电子的高灵敏度、抗噪电容式触摸解决方案
  • 检测手指在靠近电极上方 15 毫米处
  • 可以使用任何不导电材料(如玻璃或纸张)进行传感
  • 支持 IEC 61000 4-3 3 级 B 类*
    • * B 类:在嘈杂的环境中,当附近没有物体时不会误检
  • 适用于白色家电、公共设施等各种应用
  • 使用高性能、低功耗的 32 位微控制器(MCU)和触摸 IP 实现产品的系统控制和非接触式操作
  • 可以结合其他电容式应用使用非接触式控制(水位测量 + 非接触式按钮)
