[Nhcoll-l] easy way to calibrate temperature humidity sensors

[Lennart Lennuk]

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!
