GAS SENSOR, REFRIGERATOR HAVING THE SAME AND CONTROL METHOD FOR THE REFRIGERATOR

摘要

One aspect of the present invention provides a gas sensor capable of independently measuring the amount of a plurality of different target gases by having a plurality of detection units, which are discolored during a reaction with a plurality of different predetermined target gases. In addition, provided are: a refrigerator for determining the type and state of target food included in a container by sensing a color change of a gas sensor provided in the container having the target food accommodated therein; and a control method therefor. The gas sensor for detecting a plurality of target gases, according to one aspect of the present invention, comprises: a base; and a plurality of detection units arranged on the base and detecting different target gases, respectively, wherein the plurality of detection units are arranged, respectively so as to be discolored during a reaction with predetermined target gases.
