Title:
GAS DETECTION METHOD, INFORMATION PROCESSING DEVICE, PLANT DIAGNOSIS METHOD, AND PLANT DIAGNOSIS DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/219945
Kind Code:
A1
Abstract:
[Problem] To provide a gas detection method, information processing device, plant diagnosis method, and plant diagnosis device that make it possible to simply identify a specific type of gas. [Solution] In a gas detection method according to one embodiment of the present technology, a semiconductor sensor comprising an adsorption layer formed from a metal oxide is heated, the resistance value of the semiconductor sensor in an air atmosphere in which a reducing gas is present is measured, and when, in a first temperature range, the measured resistance value is higher than the resistance value of the semiconductor sensor in an air atmosphere in which the reducing gas is not present and, in a second temperature range that is higher than the first temperature range, the measured resistance value is lower than the resistance value, a determination is made that the reducing gas includes a hydrocarbon substance emitted from a plant or animal.
