Yeah the electricity output isn't the point but the fact the power generated is the raw signal. I wonder mostly about the accuracy and precision of such a sensor. Even its "not snow" triggers could be scientifically useful. Imagine if say it was sensitive enough it could identify particulates and tell where heavy metal pollutants land on the tarp.

Well I know that lysimeter based snowfall measurement systems can be a real pain for remote stations in winter, so to me this is the exciting bit.
