Grove – Touch Sensor 觸控感測器

這是一個簡單的 Touch Sensor 觸控感測器 。您可以使用它來替換傳統的按鈕。使用TTP223-B觸摸檢測器IC測量金屬墊的電容。當手指靠近時，它可以檢測電容的變化。這是與iPhone觸摸屏相同的技術。因此，您可以將金屬墊放置在非金屬表面，如塑料或玻璃板上，它仍然可以作為按鈕。這可能對需要防水的項目很有用。您還可以通過將其輕鬆放置在光滑表面後方，使其成為秘密按鈕。例如，您可以將它們放置在非金屬卡片表下，並隨意按壓桌面上的正確位置，您可以神秘地控制您的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.
