原廠 Grove - TFMini LiDAR微型單點激光雷達測距模組(114991434) 兼容 Arduino uno
Seeedstudio Grove - TF Mini LiDAR ToF (Time of Flight) Distance Sensor
https://youtu.be/orBNZnfp9Ik
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.
