UPDATE: 1/18/2016 - Okay, after running for several months in a low RH environment, the sensor drifted from 1% RH to 5%RH even though it appears the environment did not change. I replaced the sensor with a brand new one, and poof, the RH is back to 1%.
Regarding to readings, I have another sensor BMP180 which also has a thermometer and the temperature readings are different with the bmp180 one or two degrees lower. But I don't know which one of them is right. I just read values of both sensors and then take the mean value.
