DESCRIPTION
The Adafruit VL53L1X Time of Flight Distance Sensor (also known as VL53L1CX) is a Time of Flight distance sensor that has a massive 4 meter range and LIDAR-like precision. The sensor contains a very tiny invisible laser source and a matching sensor. The VL53L1X can detect the "time of flight", or how long the light has taken to bounce back to the sensor.
Adafruit VL53L1X 飛行時間距離傳感器（也稱為 VL53L1CX）是一種飛行時間距離傳感器，具有 4 米的大範圍和類似激光雷達的精度。 該傳感器包含一個非常小的隱形激光源和一個匹配的傳感器。 VL53L1X 可以檢測“飛行時間”，或光反射回傳感器所用的時間。
Since it uses a very narrow light source, it is good for determining the distance of only the surface directly in front of it. Unlike sonars that bounce ultrasonic waves, the 'cone' of sensing is very narrow. Unlike IR distance sensors that try to measure the amount of light bounced, the VL53L1X is much more precise and doesn't have linearity problems or 'double imaging' where you can't tell if an object is very far or very close.
由於它使用非常窄的光源，因此僅適用於確定其正前方的表面的距離。 與反射超聲波的聲納不同，傳感的“錐體”非常窄。 與試圖測量反射光量的 IR 距離傳感器不同，VL53L1X 更精確，並且不存在線性問題或“雙重成像”，您無法分辨物體是非常遠還是非常近。
This is the 'next generation' of the VL53L0X ToF sensor and can handle about ~30 to 4000mm of range distance, with up to 50Hz update rate. If you need an even smaller/closer range, check out the VL6180X which can measure 5mm to 200mm and also contains a light sensor.
這是 VL53L0X ToF 傳感器的“下一代”，可以處理約 30 至 4000 毫米的範圍距離，更新速率高達 50Hz。 如果您需要更小/更近的範圍，請查看 VL6180X，它可以測量 5 毫米到 200 毫米，並且還包含一個光傳感器。
The sensor is small and easy to use in any robotics or interactive project. Since it needs 2.8V power and logic we put the little fellow on a breakout board with a regulator and level shifting. You can use it with any 3-5V power or logic microcontroller with no worries. Works great with the 3.3V logic level of a Feather or Raspberry Pi, or the 5V level of a Metro 328 or Arduino Uno, this breakout is ready to work with most common microcontrollers or SBCs. and since it speaks I2C, you can easily connect it up with two data wires plus power and ground.
該傳感器體積小，易於在任何機器人或交互式項目中使用。 由於它需要 2.8V 電源和邏輯，我們將這個小傢伙放在帶有穩壓器和電平轉換的分線板上。 您可以放心地將它與任何 3-5V 電源或邏輯微控制器一起使用。 適用於 Feather 或 Raspberry Pi 的 3.3V 邏輯電平，或 Metro 328 或 Arduino Uno 的 5V 電平，此突破已準備好與最常見的微控制器或 SBC 配合使用。 並且由於它支持 I2C，因此您可以輕鬆地使用兩條數據線以及電源和地線將其連接起來。
As if that weren't enough, we've also added SparkFun qwiic compatible STEMMA QT connectors for the I2C bus so you don't even need to solder. Just wire up to your favorite micro with a plug-and-play cable to get ToF data ASAP. For a no-solder experience, just wire up to your favorite micro, like the STM32F405 Feather using a STEMMA QT adapter cable. The Stemma QT connectors also mean the VL53L1X can be used with our various associated accessories. QT Cable is not included, but we have a variety in the shop Communicating to the sensor is done over I2C with an API written by ST, so it's not too hard to port it to your favorite microcontroller. We've got Arduino and CircuitPython/Python code so you can use this sensor with an Arduino Uno, Feather M4, Raspberry Pi or anything in between!
好像這還不夠，我們還為 I2C 總線添加了 SparkFun qwiic 兼容 STEMMA QT 連接器，因此您甚至不需要焊接。 只需使用即插即用電纜連接到您最喜歡的微型設備，即可盡快獲取 ToF 數據。 要獲得無焊接體驗，只需使用 STEMMA QT 適配器電纜連接到您最喜歡的微型設備，例如 STM32F405 Feather。 Stemma QT 連接器還意味著 VL53L1X 可以與我們的各種相關配件一起使用。 不包括 QT 電纜，但我們在商店有多種與傳感器的通信是通過 I2C 使用 ST 編寫的 API 完成的，因此將其移植到您最喜歡的微控制器並不難。 我們有 Arduino 和 CircuitPython/Python 代碼，因此您可以將此傳感器與 Arduino Uno、Feather M4、Raspberry Pi 或介於兩者之間的任何設備一起使用！
