The Qwiic Distance Sensor uses the new RFD77402 Time of Flight sensor. This sensor is special in that it uses an infrared VCSEL or vertical-cavity surface-emitting laser to measure the amount of time it takes to bounce off a target. This allows low-cost millimeter readings up to 2 meters!
The VCSEL is a class 1 laser product so it is safe for almost all applications. The sensor doesn’t emit visible light but most cell phones can see it!
We’ve written an RFD77402 Arduino library available for download through the integrated Arduino library manager.
The Qwiic system enables fast and solderless connection between popular platforms and various sensors and actuators. You can read more about the Qwiic system here. We carry 50mm, 100mm, 200mm, 500mm, and breadboard friendly Qwiic cables.
We do not plan to regularly produce SparkX products so get them while they’re hot!
Experimental Product: SparkX products are rapidly produced to bring you the most cutting edge technology as it becomes available. These products are tested but come with no guarantees. Live technical support is not available for SparkX products. Head on over to our forum for support or to ask a question.

Qwiic 距離傳感器使用新的 RFD77402 飛行時間傳感器。該傳感器特別之處在於，它使用紅外 VCSEL 或垂直腔表面發射激光器來測量反彈目標所需的時間。這允許高達 2 米的低成本毫米讀數！
VCSEL 是 1 類激光產品，因此對於幾乎所有應用都是安全的。傳感器不發出可見光，但大多數手機都可以看到它！
我們已經編寫了一個 RFD77402 Arduino 庫 ，可通過集成的Arduino圖書館管理員下載。
Qwiic 系統可實現流行平台和各種傳感器和執行器之間的快速無焊接連接。您可以在這裡閱讀有關Qwiic系統的更多信息。我們攜帶 50mm ， 100mm ， 200mm ， 500mm 和 麵包板友好的 Qwicic電纜。
我們不打算定期生產SparkX產品，讓他們在熱的時候！
