Abstract: A gas sensor module, a refrigerator having the same and a control method for the refrigerator. In another aspect, in a gas sensor module, ion pairs are pre-dissolved in an aqueous solution while the amount thereof and pH of an initial aqueous solution may be adjusted to adjust a sensing range and sensitivity with respect to a target gas to be sensed. In another aspect, the gas sensor module senses the amount of target gas includes an aqueous solution in which ion pairs of a substance having the same dissociation constant as the target gas are dissolved, and senses a pH change of the aqueous solution that occurs due to the target gas being dissolved in the aqueous solution.

Abstract: 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.
