2.8 Chlorophyll sensor
Principle:
Chlorophyll is an important biochemical molecule that is the basis of photosynthesis and uses solar
energy to produce oxygen. The concentration of suspended phytoplankton can usually be calculated by
collecting the amount of chlorophyll in the water sample.
The chlorophyll sensor in utilizes the characteristic that chlorophyll A has absorption peak and emission
peak in the spectrum. Monochromatic light emitting a specific wavelength is irradiated into water, and
chlorophyll A in water absorbs the energy of the monochromatic light, releasing another wavelength. The
monochromatic light, the light intensity emitted by chlorophyll A is proportional to the amount of
chlorophyll A in the water. From this, the concentration of chlorophyll in the water body was calculated.
The appearance of the chlorophyll sensor is shown in Figure 10.
