WebIf you use a good capacitive polymer sensor for relative humidity, you can achieve a calibration uncertainty for the moment of calibration which is only slightly lower (0.3 % to 0.5 % with k=2). Web18 aug. 2024 · Relative humidity represents the extent to which air is saturated with moisture at a given temperature. When raising plants, you should have some idea of the relative humidity, especially in the winter. If you get a shock from a spark every time you touch something, it is certainly too dry.
