摘要： A gas sensor includes a plurality of detectors discolored by reacting with different predetermined target gases, such that the gas sensor independently measures the amount of each target gas. A refrigerator for deciding a type and state of target food contained in a container by sensing a color change of a gas sensor mounted to the container including the target food, and a method for controlling the gas sensor are disclosed. The gas sensor for detecting a plurality of target gases includes a base and a plurality of detectors provided at the base. The detectors respectively detect different target gases, and each detector is discolored by reacting with each predetermined target gas.
