The TF Mini LiDAR is an unidirectional laser range finder based upon
time-of-flight (ToF) technology. It consists of special optical and electronic devices, which integrates adaptive algorithm for
indoor and outdoor application environment. It has tiny body and high performance in
distance measurement.
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.

NOTE:
The product may be invalid when probing objects with high reflectivity, such as mirrors and smooth tiles.
When there are transparent objects, such as glass and water, between the product and the tested object, it may become invalid.
Do not touch the circuit board with your bare hands. If necessary, please wear an electrostatic wristband or antistatic gloves.
