Dragino LLDS40 User Manual

The detection angle of the LLDS40 is 3 degrees, and the size of the light spot at different distances is the
side length of the detection range. The size of the light spot at different distances is the side length of the
detection range. The side length of the detection range (the shape is square), as shown.

Note that generally, the side length of the detected target object should be greater than the side length of
the detection range of the LLDS40; when the detected object is smaller than the detection range side
length; when the detected object is smaller than the detection range side length, the effective range of the
radar will be reduced.
3.3 !Notice of usage:
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.
