It's Snowing!!!

[Stuart Grimshaw <stuart.grimshaw@xxxxxxxxx>]

I'm sitting here in the office, watching the snow, looking accross the
valley I can see the hills got more and more covered in snow. The
problem is I live up on those hills, and I could do with knowing just
how deep the snow is.

I've considered using a webcam, but it's a bit tricky to tell the depth of
snow.

I don't suppose anyone does this already do they?

Perhaps a moisture sensor would detect the rain/snow in conjunction
with a temp. sensor outdoors would tell you if it actually was snowing
or raining, but wouldn't give you any idea of depth.

Could you mount a sensor vertically, and as the snow mounted up the
resistance would drop? How would you avoid detecting a drift as a
massive amount of snow?

You couldn't use a normal rain guage either, unless you had a heater
element to melt the snow.
