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.

Gas sensor, refrigerator including same and control method therefor

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.

Gas sensor module, refrigerator having the same and control method for the refrigerator

A gas sensor, a refrigerator having the gas sensor, and a method for controlling the gas sensor recognizes the ripening degree of a target food on the basis of a variation in color using a pH indicator having a color that is changed with pH variation generated when the pH indicator reacts with target gas, a refrigerator having the gas sensor. The gas sensor for detecting target gas includes: a base provided for gas permeation; and a detection unit provided at the base, and is discolored in response to pH variation generated when reacting with target gas having permeated the base.

Disclosed is a microfluidic chip capable of accurately and quickly detecting presence of a trace amount of a target within a fluid sample. It has a channel structure comprising a sample inlet for feeding a sample therethrough, a first reservoir for primarily storing the sample therein, a second reservoir for secondarily storing the sample therein, a first reaction portion in which a target is conjugated with a label, a second reaction portion in which the labeled target undergoes a specific reaction, such as an antigen-antibody reaction, and a delaying portion, located between the first and the second reaction portion, for decreasing a flow rate of the sample.
