PRODUCT DETAILS

Description

The TF Mini LiDAR is based on the 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.

How does a Time of Flight Sensor Work?

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. 

ToF sensors use a tiny laser to fire out infrared light where the light produced out will bounce off any object and return to the sensor. Based on the time difference between the emission of the light and its return to the sensor after being reflected by an object, the sensor is able to measure the distance between the object and the sensor.

Applications

• Drone altitude holding and terrain following

• Machine control and safety sensor

• Robot distance detection

If you are using Seeeduino Lotus then just connect it with the Grove Serial Interfaces.
