Abstract
A physical quantity detection device that can improve arithmetic resolution while preventing an increase in memory capacity is obtained. A physical quantity detection deviceaccording to the present invention includes: a physical quantity detection sensor that detects a physical quantity of a measurement target gas; a storage unit that records a correction amount corresponding to a detection value of the physical quantity detection sensor; and an arithmetic unitthat performs output adjustment of the detection value using the detection value and the correction amount. Resolution of the storage unitis lower than arithmetic resolution of the arithmetic unit
