The paper is also attached.  I've included a picture of the setup I use for controlled humidity experiments. I use a HOBO sensor to monitor the humidity and temperature, inside the lid.

Hi!



In our herbaarium we have one quite old and one new temperature humidity sensor.

The data is quite diferent though these sensors are placed in the same spot.



Do you know any good and cheap ways to calibrate those senors?



Best regards!
