The present invention provides a gas sensor module capable of improving selectivity and sensitivity with respect to a target gas by measuring pH change of an aqueous solution by dissolving the target gas in the aqueous solution, a refrigerator having a gas sensor module, and a method to control a refrigerator. Moreover, the present invention provides a gas sensor module capable of adjusting the sensitivity and a measuring range with respect to a measurement target gas by adjusting the pH of the initial solution and the amount while counter-ions are dissolved in an aqueous solution in advance, a refrigerator having a gas sensor module, and a method to control a refrigerator. According to the present invention, the gas sensor module to measure the amount of predetermined gas includes an aqueous solution in which counter-ions of a material having a dissociation constant (pKa) which is the same as the predetermined gas are dissolved, and adjusts a pH change of the aqueous solution generated by dissolving the target gas in the aqueous solution. |
