I was at kmart in the tool section. I noticed an indoor/outdoor thermometer similar to the one pictured below. It was about $20 and displays Indoor Temperature and humidity and outdoor temperature. I placed the remote sensor in the basement where my bottles will be stored. The main unit is upstairs where the fermenting and bottling will take place. It is battery operated so I can take the main unit downstairs to check humidity.
Upstairs: 69 degrees 30% humidity
Downstairs: 60 degrees
