摘要 |
A dew-sensing hygroscopic element includes a pair of electrodes and a dew-sensing hygroscopic material arranged between the electrodes which detects dew by the change of impedance between the electrodes. The dew-sensing hygroscopic material comprises polyvinyl alcohol having a saponification equivalent of 20 to 65 as a base material and contains an organic electrolyte.
