Abstract: According to one embodiment, a sensor includes a sensor section and a circuit section. The sensor section includes a first element portion including a first resistance element and a first conductive member, and a second element portion including a second resistance element. The circuit section includes a detector and a controller, and is configured to perform a first operation. The controller controls a first power in the first operation based on a second signal corresponding to a second resistance of the second resistance element. In the first operation: the controller supplies the first power to the first conductive member to increase a first temperature of the first element section; and the detector outputs a detected value corresponding to a difference between the second signal and a first signal corresponding to a first resistance of the first resistance element in a first state in which the first temperature is raised.

Abstract: According to one embodiment, a data processing device includes an acquisitor and a processor. The acquisitor can acquire a first concentration signal obtained from a first concentration sensor configured to detect a first concentration of a first target substance included in a first output gas and a first flow rate signal obtained from a first flow rate sensor configured to detect a first flow rate of the first output gas. The processor can derive a first concentration value corresponding to the first concentration based on the first concentration signal. The processor can derive a first corrected conversion coefficient obtained by correcting a first conversion coefficient regarding a relationship between the first flow rate signal and the first flow rate based on the first concentration value. The processor can derive a first flow rate value corresponding to the first flow rate based on the first flow rate signal.
