Abstract: 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 gas sensor (10) that performs concentration measurement of a measurement target gas in air; a heater (17) that heats the gas sensor; an air intake port (11) and an air discharge port (12) that are connected to the gas sensor; and a control device (20) that performs heating control of operating the heater so as to heat the gas sensor. The control device acquires temperature information for the gas sensor and temperature information for a space from which the air intake port takes in air and performs the heating control based on the temperature information for the gas sensor and the temperature information for the space from which the air intake port takes in air.

Abstract: 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.

Abstract: Provided is an apparatus with a gas detection function capable of detecting a detection target gas with high accuracy. An apparatus with a gas detection function comprises: a housing (10); a vibration source (20); and a gas measurement unit (40) located inside the housing and demarcated by a partition, wherein the vibration source is located outside the gas measurement unit, the gas measurement unit includes a detector (41) located on a substrate (30), and a gas detection space (42) provided with a hole (43) through which a gas passes, and a frequency f expressed by the following Formula (1): f = c 2 ? ? ? S VL Formula ? ( 1 ) is 500 Hz or more, where V is a volume of the gas detection space, S is a cross-sectional area of the hole, L is an effective length of the hole, and c is a sound speed.
