SHT_75 with picbasic pro

[Dave]

Ambrogio, Thats OK, as I am no expert myself... I personally don't bother with the humidity information here in Michigan when the temp's are below freezing.. Only the wind chill factor... There is a lot of information on Dew Points and Humidity on the web. I only hope I was able to help out... 73's for now...

Hi Dave,
I red your explanation carefully: it is very clear to me now. I did not get those points before.
I thank you very much for your help on the matter.
Bye
73!

Another item for the RH sensor...
This is the explanation provided by the sensor manufacturer ( Sensirion ):

Thank you for your e-mail. The SHT75 can measure RH below 0°C. However as cold air below 0°C contains only a small amount of water molecules it is very difficult to measure them accurately. Therefore tolerances increase.

Hope this answers your question.

Best regards
