Yep! So far I couldn't find on the internet the formula for the Davis polymer humidity sensor. Are we the first ones? Again??? This I found here: https://www.davisinstruments.com/product_documents/weather/spec_sheets/7859_spec_Rev_D.pdf *"The humidity sensor is a thin film capacitor element. A dielectric polymer layer absorbs water molecules from the* *air through a thin metal electrode, which causes a change in capacitance proportional to relative humidity."* Luc
