Product review (1 stars): Humidity indicator stuck at 15%
The relative humidity appears to be stuck at 15%.  I set the unit outside where the humidity is 42% according to the weather channel and it still doesn't move off of 15%.  The temperature appears to function correctly.  I wish I had read some of the reviews before I purchased the unit because I wanted it for the humidity measurement for my indoor plants.  Oh well, live and learn.
