Description
Chlorophyll sensor utilizes the characteristic that chlorophyll A has absorption and emission peaks in the spectrum, emitting monochromatic light of specific wavelengths
Shooting into water, chlorophyll A in the water absorbs the energy of this monochromatic light and releases another wavelength of monochromatic light. The intensity of light emitted by chlorophyll A is directly proportional to the content of chlorophyll A in the water.
