Abstract

The present invention relates to a gas sensing device. In the present invention, a processor (20), a first gas sensor (30), and a second gas sensor (32) are installed on a substrate (10). The first gas sensor (30) and the second gas sensor (32) are positioned between the two ends of the processor (20) and the corresponding edges of the substrate (10), respectively. A temperature/humidity sensor (34) is installed on the substrate (10), and a through channel (12) is formed through the substrate (10) between the temperature/humidity sensor (34) and the processor (20). The first gas sensor (30) and the second gas sensor (32) detect the types and concentrations of a plurality of gases, respectively, and the processor (20) detects a mixed gas and analyzes the types and concentrations of each gas of the detected mixed gas using a deep learning model. At this time, the learning model uses a first-stage classification model and a second-stage regression model.
