Description (From Recipaedia)
Hygrometer displays humidity of the surroundinga area. It is an important tool when planting trees. All trees need a lot of humidity to grow. When a tree is planted an area which is too dry, the sapling will wilt. It is also an electric element that outputs analog signal corresponding to the surrounding humidity.
This must be an old-fashioned type of hygrometer and actually displays the dryness rather than the humidity. A higher humidity drives the needle to the left and a drier reading moves the needle to the right.The hygrometer can be connected to an electric circuit and will output an analog signal proportionate to the humidity:
- 1.14- Added the Hygrometer. Its uses are to show humidity so trees could grow.
- 1.23- Hygrometers now produce an analog signal.
