DHT22 Humidity datalogger
by luckyresistor.me: There is a large cellar where I could store unused items and documents, but the catch is the humidity there. It is a root cellar near a small brook and the humidity varies between 75% up to 90%. Archived material should never be exposed to humidity greater...
