Title:
PHYSICAL QUANTITY DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/024710
Kind Code:
A1
Abstract:
Provided is a physical quantity detection device that can improve computational resolution while suppressing increases in memory capacity. A physical quantity detection device 100 according to the present invention is characterized by: comprising a physical quantity detection sensor that detects the physical quantity of a gas to be measured, a storage unit that records a correction amount corresponding to the detection value from the physical quantity detection sensor, and a calculation unit 110 that uses the detection value and the correction amount to perform output adjustment on the detection value; and the resolution of the storage unit 120 being lower than the computational resolution of the calculation unit 110.
