Here"s a neat little device that will answer a very common question: "How"s the Weather" This little monitor will display the temperature in either Fahrenheit or Celsius, and the internal battery charges using the solar panel on the back, so you never have to replace batteries. Along with the temperature it also displays the % humidity. A pivotal suction cup allows you to put this on the inside of a window to monitor the room"s temperature, or you can flip it around and stick it to the outside of the window with the monitor facing into the house so you can monitor the temperature outside.
