Abstract
A humidity detector includes a first heat-sensing element for an electric signal corresponding to the temperature of steam to be detected and a second heat-sensing element for an atmosphere temperature whose vapor is to be detected or a temperature close to it. A comparator compares the electric signals from the first and second heat-sensing elements. The vapor detection characteristics may be adjusted through variation in the heating temperature of the first heat-sensing element.
