The chlorophyll sensor utilizes spectral analysis technology, emitting monochromatic light at chlorophyll's absorption peak wavelength. Chlorophyll in water absorbs this light energy and emits light at its characteristic emission peak. The intensity of emitted light is directly proportional to chlorophyll concentration, enabling precise measurement from 0-500 μg/L with 0.01 μg/L resolution.
