Method for sensing volatile fatty acid and device for measuring volatile fatty acid

A device for measuring volatile fatty acid, the device comprising a resistance measurement device, a humidity measurement means, a data extraction means, and a data analysis means, wherein

• the resistance measurement device is configured to include at least two electrodes disposed to be adjacent to each other at a small spacing on an insulating substrate, to measure an electrical characteristic caused by electrical resistance between the at least two electrodes, and to output an obtained result,
• the humidity measurement means is arranged to be adjacent to the resistance measurement device, and is configured to measure a relative humidity of a space near the at least two electrodes of the resistance measurement device, and to output an obtained result,
• the data extraction means is configured to extract output data from the resistance measurement device when the relative humidity measured by the humidity measurement means satisfies a predetermined humidity condition, and
• the data analysis means is configured to compare the output data extracted by the data extraction means with calibration curve data obtained in advance, and to output an obtained result.
