1. What is the relationship between the ranging value and the color of the object?
Answer: The higher the reflectivity of the color object, the longer the effective distance of ranging. The higher the reflectivity of the object, the longer the accurate and effective range of ranging. Calibration is to eliminate the offset and crosstalk of the cover window. For example, the gray target has a shorter effective range than the white target. The maximum distance in the ranging parameter is also based on the white object. Please actually measure objects of other colors.

3. Is the ranging value related to the size of the target object?
Answer: Yes, accurate ranging requires that the ranging target covers FOV to maximize sensor reception and make the ranging accuracy higher. Combining FOV and actual distance can calculate the height of the ideal target. Please refer to the ideal target height in the specification for application.

4. Precautions for use:
A. The measured object and the sensor are as parallel as possible. If there is a deviation, the deviation angle cannot be greater than the laser emission angle.
B. To detect fast moving objects, the sampling frequency of the module should be adjusted.
C. The laser light source is a beam type laser that is invisible to the naked eye. Obstacles other than the object to be measured within the emission angle of the light source will affect the ranging effect.
D. The module is affected by natural light. Generally speaking, the stronger the natural light, the greater the impact, which manifests as the shorter the ranging distance, the worse the accuracy, and the greater the fluctuation. Under strong light conditions (such as sunlight), it is generally recommended to use it in close-range detection scenes.
