Correcting humidity data readings
I'm trying to find a formula that can help me with a project I'm building and hope that you can help.
I'm taking humidity data readings through sensors, but have found errors occurring as the humidity sensors are temperature sensitive, and need to add temperature compensation to ensure the readings remain accurate.
For example, at 20 deg C, the humidity sensor reads 270, whilst at 30 degrees C, the same sensor reads 237. Both sensor readings should be identical.
Unfortunately, the error is not linear, as the error percentage reduces as the temperature increases.
Any formula would be included within the computer software, but having wrestled with this most of tonight, I have not got anywhere near a solution or a way forward.
It's time like this that I wish I'd paid more attention in class!!
