## Description

#### Introduction

 The TF Mini LiDAR is an unidirectional laser range finder based upon [time-of-flight (ToF) technology](https://www.dfrobot.com/index.php?route=product/search&search=ToF&description=true). It consists of special optical and electronic devices, which integrates adaptive algorithm for [indoor](https://www.dfrobot.com/index.php?route=DFblog/blogs&search=indoor) and outdoor application environment. It has tiny body and high performance in [distance measurement](https://www.dfrobot.com/search-distance%20measurement.html). 

 The laser sensor can be used as a distance-measuring tool to detect the distance from it to obstacles. It can also be used as an eye of a robot; it provides distance information for robotic safe avoidance and route selection. It supports for system automation in a variety of machine control scenarios. Because of its small size, light weight and low power consumption, it is also suitable for altitude hold quad-copters and terrain following.
