I am looking for a laser (lidar) distance measurement for outdoor use even in sunlight. I don't want ultrasound, I have it to measure the height of the snow, and the ultrasound waves are absorbed by the snow. So laser (lidar).
Unfortunately, what I found behind the sensors, they are completely non-functional in sunlight. Don't you know something please?
I have used several of the Pololu TOF sensors but always indoors
could you shroud the sensor from direct sunlight?
try a web search for capacitance level sensors
There is a government agency in the USA called NASA ( National Aeronautics and Space Administration ), they have the same problem. Check this link: Technique to separate lidar signal and sunlight | NASA Airborne Science Program
Scattered, I believe.
Military, surveyors and carpenters use LRD (LDR) in daylight.
Many commercial snow depth sensors use ultrasonic sensors mounted above the snow. Suggest researching what frequencies they use. May not be the frequency of the inexpensive ultrasonic sensors commonly used with Arduinos.
Or just buy one fit for purpose. See Maxbotics, for example.
