SparkFun Distance Sensor 距離傳感器 - 1.3 Meter 1.3米, VL53L4CD (Qwiic) SEN-18993
This SparkFun Distance Sensor Breakout utilizes the VL53L4CD next generation ToF (Time of Flight) sensor module to give you the highly accurate measurements at short ranges for its size. The VL53L4CD from STMicroelectronics uses a VCSEL (Vertical Cavity Surface Emitting Laser) to emit an infrared laser to time the reflection to the target. That means that you will be able to measure the distance to an object from 1mm to 1300mm away with millimeter resolution! To make it even easier to get your readings, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system so no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1”-spaced pins in case you prefer to use a breadboard.
這款 SparkFun 距離傳感器分線器採用 VL53L4CD 下一代 ToF（飛行時間）傳感器模塊，可為您提供針對其尺寸的短距離高精度測量。STMicroelectronics 的 VL53L4CD 使用 VCSEL（垂直腔面發射激光器）發射紅外激光以定時反射到目標。這意味著您將能夠以毫米分辨率測量到 1 毫米到 1300 毫米距離的物體的距離！為了更輕鬆地獲取讀數，所有通信均僅通過 I 2 C 進行，使用我們方便的 Qwiic 系統，因此無需焊接即可將其連接到系統的其餘部分。但是，如果您更喜歡使用麵包板，我們仍然斷開了 0.1 英寸間距的引腳。
Each VL53L4CD sensor features a precision to be 1mm with an accuracy around +/-7mm (white target: 88%, indoor, no infrared) and a minimum read distance of this sensor is 1mm. The field of view for this little breakout has a typical full field of view of 18° with a read rate of up to 100Hz. Make sure to power this board appropriately since it will need 2.6V-3.5V to operate. Lastly, please be sure to remove the protective sticker on the VL53L4CD before use otherwise it will, most assuredly, throw off your readings.
每個 VL53L4CD 傳感器的精度為 1 毫米，精度約為 +/- 7 毫米（白色目標：88%，室內，無紅外線），該傳感器的最小讀取距離為 1 毫米。這個小突破的視野具有 18° 的典型全視野，讀取速率高達 100Hz。確保為該板供電，因為它需要 2.6V-3.5V 才能運行。最後，請務必在使用前撕掉 VL53L4CD 上的保護貼紙，否則肯定會影響您的讀數。
Note: This is a CLASS 1 LASER PRODUCT CLASSIFIED IEC 60825-1 2014.
注意：這是 1類激光產品分類 IEC 60825-1 2014。
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
SparkFun Qwiic 連接系統是一個由 I 2 C 傳感器、執行器、屏蔽層和電纜組成的生態系統，可加快原型製作速度並減少出錯的可能性。所有支持 Qwiic 的電路板都使用通用的 1mm 間距、4 針 JST 連接器。這減少了所需的 PCB 空間量，並且極化連接意味著您不能錯誤地連接它。

Note: The I2C address of the VL53L4CD is 0x29 and is hardware defined. A multiplexer/Mux is required to communicate to multiple VL53L4CD sensors on a single bus. If you need to use more than one VL53L4CD sensor consider using the Qwiic Mux Breakout.
VL53L4CD的 I 2 C 地址為 0x29，由硬件定義。需要一個多路復用器/Mux 來與單個總線上的多個 VL53L4CD 傳感器進行通信。如果您需要使用多個 VL53L4CD 傳感器，請考慮使用Qwiic Mux Breakout。
