Of course one could, and the chip would give you the same information on the
humidity the wood will take under the prevalent conditions, but it won't tell
you what to do - change the humidity, or the temperature, or both. A relative
humidity of 45 % will be too dry at temperatures of 25 Celsius or higher, (no,
I am not going to convert that into F), but you can rectify the situation by
getting the room temperature down. It is like with watches - the analog
information is better.
