I am working on a dew point sensor, and I am using the Arduino Uno board with the DHT22 sensor. I have it taking a reading once ever 2 seconds and I am using the DHT.h library. The problem I am having is when I compare the values to our standard here the Humidity reads high and the Temp reads low. Is there anyway to get the values to read closer to what the standard is?
Using a RH and Temp Calibrator I had access to I was able to get better results by all lines to adjust the RH and Temp to a better value. Basically a correction equation.
