A pickled vegetables fermentation detector is the sensor for sensing kimchi curing which converts variables depending on the state of kimchi curing into an electric signal and is provided with an air bubble generator, gas collector and detector, in which the inside of the air bubble generator is divided into an upper compartment and lower compartment; gas generated in curing pickled vegetables is collected in the upper compartment to a predetermined quantity and gas is transported to the lower compartment at a predetermined pressure, and the main body of the lower compartment connected to one side of the upper compartment is composed of an air bubble homogeneity device expanded to the lower portion and inserted to a predetermined fluid in the inside of the lower compartment; one wall of a pair of oppositely disposed side walls is thicker than the other, and thickness of the walls is cut off at a predetermined height in the lower wall of both walls and a transparent panel is installed in the proximity of those walls; therefore a groove is formed with a "U"-shaped form, which includes an air bubble detector depending on the kimchi curing state, and is equal in size to the groove, is inserted in the groove. In the main body a light emitting element of a photocoupler including a detector of air bubbles is included on a transparent board formed on the groove of one side wall so that detection of air bubbles is accurately performed depending on generation of air bubbles and on the other side the light receiving element is installed so as to interact with the light emitting element.
