HUMIDITY SENSOR AND HUMIDITY SENSOR DEVICE

WIPO Patent Application WO/2018/139142

A1

Provided is a humidity sensor that makes highly accurate humidity detection possible even if the applied voltage changes, an arbitrary voltage is applied, or thermistors having different characteristics are used. A humidity sensor according to the present invention is provided with a detection chamber part 2, a first standard chamber part 3, a separate gas chamber part 4, and a second standard chamber part 5 that are disposed so as to be close to each other. The detection chamber part is provided with a detection container having a through hole through which outside air can be introduced into the internal space of the detection container and a detection thermistor 7 installed inside the detection container. The first standard chamber part is provided with a first standard container having dry air sealed therein and a first standard thermistor 9 installed inside the first standard container. The second standard chamber part is provided with a second standard container having dry air sealed therein and a second standard thermistor 13 installed inside the second standard container. The separate gas chamber part is provided with a separate gas container having a gas sealed therein that has a different thermal conductivity from that of said dry air and a separate gas thermistor 11 installed inside the separate gas container.
