Provided are a gas sensor system, a gas sensor control device, and a control method that enable high-accuracy measurement without causing a user to wait. The gas sensor system (1) includes: a reception section (30) that receives a startup signal from externally to the gas sensor system; a gas sensor (10) that performs concentration measurement of a measurement target gas in air; an air intake port (11) and an air discharge port (12) that are connected to the gas sensor; at least one fan (13); and a control device (20) that starts up the gas sensor through reception of the startup signal, that acquires temperature information for the gas sensor, and that, based on the temperature information for the gas sensor, performs cooling control of operating the fan so as to cool the gas sensor from startup of the gas sensor, before initiation of the concentration measurement.

This application claims priority of Japanese Patent Application No. 2022-050733 (filed Mar. 25, 2022) and Japanese Patent Application No. 2023-036059 (filed Mar. 8, 2023), the entire contents of which are incorporated herein by reference.
The present disclosure relates to a gas sensor system, a gas sensor control device, and a control method.
Infrared light in a long wavelength band typically having a wavelength of 2 μm or more is used in gas sensors and the like due to a thermal effect thereof and an effect of infrared light absorption by gases. For example, non-dispersive infrared (NDIR) gas sensors are used to measure the concentration of a gas through detection of the amount of absorption of infrared light by exploiting the fact that the wavelength of infrared light that is absorbed differs depending on the type of gas (for example, refer to Patent Literature (PTL) 1).
