DHT11 - temp ok, but RH values wildly off

rdibened:
Here is my fix, I warn you that I am still testing. My DHT22 connected to my Arduino Uno reads 16% less that a know good humidity gauge. I did the following

float h = dht.readHumidity();
h=h+16.0;

Added the h=h+16.0

So far the reading is accurate. I just started testing and need to burn in the fix for several days or weeks to see if it is carries through the range of humidity I will be reading.

I think that this is a bandaid to the real problem but it is quick and dirty and so far it works. I would like to hear your thoughts.

Not sure about that.
now it's reporting 19% while it's 45/50% in this room...
