Blue-green algae (BGA), also known as cyanobacteria, can range in colors from blues, greens, reds, and black. Blue-green algae can reduce nitrogen and carbon in water, but can also deplete dissolved oxygen when overabundant. Monitoring Blue-green algae is important because they pose a serious threat to water quality, ecosystem stability, surface drinking water supplies, and public health through toxin production and the large biomass produced in algal blooms.
The Blue-green algae sensor utilizes the characteristic that Blue-green algae A has an absorption peak and an emission peak in the spectrum. When the spectral absorption peak of Blue-green algae A is emitted, monochromatic light is irradiated into the water, and Blue-green algae A in the water absorbs the energy of the monochromatic light, and is released. Another monochromatic light with a wavelength emission peak, the light intensity emitted by Blue-green algae A is proportional to the content of Blue-green algae A in water. The sensor is easy to install and use. Blue-green algae universal applications monitoring in water stations, surface waters, etc.
