<p>The present invention relates to a biosensor for detecting water microorganisms. The biosensor includes a sensor module that includes a light source unit which repeatedly performs light irradiation and stops light irradiation, a passage section which is provided on a front surface of the biosensor, passes the light emitted from the light source unit out of the biosensor, and passes fluorescent light reflected from the microorganisms into the biosensor, and a detection unit which detects the passing fluorescent light while the light irradiation from the light source unit stops; and a case that protects the sensor module in the water. According to the biosensor and a sensing method thereof, the light is intermittently emitted and the reflected light is detected with a deviation, and thus the light source unit can be used for an extended period of time. Accordingly, biosensor maintenance costs can be saved. In addition, a module including the light source unit is simplified and is configured to be removable, and thus biosensor maintenance efficiency can be improved. Also, the present invention can be applied to not only water quality inspection and water quality control but also other various fields for irradiating and detecting microorganisms with light.</p> |
