++Possible invalid /wrong reading for LiDAR ToF tech:
++
++* Measure high reflectivity object such as: Mirror, Smooth ceramic tile, static milk surface, will have possible wrong readings.
++* While there is transparent object such as glass, water drop between the measured object and the LiDAR sensor, the reading might be wrong.
++* The LiDAR probe is cover by dirty things; the reading might be wrong. In this case, need to clean the probe.
++* The sensor window is made by Acrylic. Don't touch it with alcohol material. This will destroy the sensor window.
