Darrel,

Should have done a search first!

Thanks!

Charles,

If your interested I have working code that will give you a 100th of a percent in RH and a 100th of a percent in temperature for the full range of the sensor in Celsius, Fahrenheit and Kelvin. I also have code for checking the CRC thanks to Tom Estes. NavMicroSystems works fine but doesn't appear to handle negative temperatures though. If you're interested let me know and I'll post it when I get back to the office.

I'm interested. I have enough to do withought debugging even more code. Anything you could send would be greatly appreciated. If you want to send off-forum, I'll send you a private post with info.

Charles, you have perked my interest with you claims. I am definitely interested in hearing about your approach.

I have made many claims, but not about the Sensirion! I think you are requesting the code that CocaColaKid is talking about.

The code was too long to post so I just attached it in a TXT file instead. I also included the data information that corresponds to the data output from the sensor. I used this information to verify my code math was correct. Hope this helps you guys out. If you have any questions please feel free to ask.

Thank you CocaColaKid. Your code works fine. But it takes 3 seconds to refresh data. Is there a way to reduce this time to a second? (with pic16f628a)
