Abstract

A physical quantity measuring device is configured to measure a physical quantity of a fluid. The physical quantity measuring device includes: at least two humidity detection parts configured to output a humidity signal corresponding to a humidity of the fluid; and an abnormality determination part configured to determine that an abnormality has occurred in the humidity detection parts in response to that a difference between the humidity signals obtained from the two humidity detection parts exceeds an abnormality determination threshold.
