This product is based on ToF (Time of Flight) principle and integrated with unique optical and electrical designs, so as to achieve stable, precise, high sensitivity and high-speed distance detection.
ToF is the abbreviation of Time of Flight technology, and its operating principle is as follows: a modulated near-infrared light is sent from the sensor and reflected by an object; the distance to the object to be shot can be converted with the sensor by calculating the time difference or phase difference between the light sending and the light reflection, so as to produce the depth information.
Applications:
• Drone altitude holding and terrain following
• Machine control and safety sensor
• Robot distance detection
If you are using Seeeduino Lite then just put it straight into the Grove Serial Interfaces.

該產品基於ToF(飛行時間)原理,集成獨特的光電設計,實現穩定,精確,高靈敏度,高速度的距離檢測。
ToF是飛行時間技術的縮寫,其工作原理如下:調製後的近紅外光從傳感器發出,被物體反射;通過計算光發射與光反射之間的時間差或相位差,可以通過傳感器轉換到被攝物體的距離,從而產生深度信息。
應用:
•無人機高度保持和地形跟隨
•機器控制和安全傳感器
•機器人距離檢測
