Working principle for a capacitive humidity sensor. A The initial setup of the capacitive sensor indicating no detectable voltage across the plates. B The introduction of water vapor in the atmosphere. (C) The change in the permittivity of the dielectric because of the water vapor, generating a detectable voltage across the plates.  (Source: Alam et al. 2021)
