The snow will be flying up here in New England in the not to distant future and this year I want to try building a snow depth sensor. I have found a commercial sensor based on ultrasound for around $150 and a few internet posts using the relatively inexpensive Parallax Ping sensor.
Has anyone tried using the Parallax 28044 laser range finder to measure snow depth? This sensor has a 2 meter range which would work quite well for measuring normal snow fall amounts around here. However, snow being what it is I wonder if the laser would reflect consistently off the surface so it could be measured accurately, say +/- 1-2 mm. At $100 it is a bit too pricey to buy just to see if it might work.
