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.
