描述
Grove Touch Sensor 觸摸感測器
Grove Touch Sensor 簡單的觸摸傳感器模組。您可以使用它來代替傳統的按鈕。使用 TTP223-B 觸摸檢測器 IC 它測量金屬焊盤的電容。當手指靠近時，它可以檢測電容的變化。這與i Phone 觸摸屏中使用的技術相同。因此，您可以將金屬墊放置在非金屬表面（如塑料或玻璃板）下，並且仍然可以作為按鈕使用。這對於需要防水的項目可能是有用的。您也可以通過將其放置在光滑的表面後隱秘的按鈕。比如你可以把它們放在一個非金屬的卡片桌子下面，然後在桌面上隨意地按下正確的位置，就可以神秘地控制你的DIY項目。

Grove Touch Sensor
This is a simple touch sensor module. You can use it to replace a traditional push button. Using the TTP223-B touch detector IC It measures the capacitance of a metallic pad. It can detect the change in capacitance when a finger is near it. This is the same technology used in the iPhone touch screen. So you can place the metallic pad under a non-metallic surface such as a plastic or glass sheet and it will still work as a button. This may be useful for projects that need to be waterproof. You can also make a secret button by placing it inconspicuously behind a smooth surface. For instance you could place them under a nonmetallic card table and by casually pressing the right location on a tabletop surface you could mysteriously control your DIY project. Features
