PURPOSE: A light sensor device for measuring a water quality using an RGB sensor is provided to integrate light emitting diodes, the RGB sensor, and a light source filter into a sensor holder and to detachably insert the sensor holder into a sensor casing, thereby miniaturizing and lightening the sensor device at low costs.;CONSTITUTION: A light sensor device (10) for measuring a water quality using an RGB sensor (11) includes light emitting diodes (9), a light source filter (12), a fluorescent film (8), a substrate (7), a fluorescent filter (13), and a measurement device. The light emitting diodes are installed on the front end surface of a sensor holder (14) at a predetermined interval. The light source filter is installed between the outer periphery of a light collecting pipe (14a) and the inner periphery of a sensor casing (1) and controls the frequencies of lights emitted by the light emitting diodes. The fluorescent filter emits the fluorescence of a specific frequency by reacting with the lights projected via the light source filter. The fluorescent film is coated on the substrate, and the substrate is installed inside a front cap. The fluorescent filter is installed inside the front end portion of the light collecting pipe and controls the frequencies of the fluorescence emitted by the fluorescent film. The measurement device is composed of the RGB sensor. The RGB sensor is arranged on the center of the sensor holder and inserted inside the sensor casing. The RGB sensor directly detects the colors of the light projected via the fluorescent filter, thereby measuring dissolved oxygen or pH.;COPYRIGHT KIPO 2013
