Product review (5 stars): Gives Temp and Relative Humidity
Does what I need it to do which is to tell me if the humidity is too high for storing items and for dust mites, mold, etc
I have a dehumidifier and it seems to be lowering the humidity. I have several appliances that give the temp and they are all  a few degrees apart.... So I can't be sure, but I can get the general idea.
This item does tell me whether the humidity has increased or decreased, which is what I needed.
