The HAI sensor (Harmful Algal Indication sensor) is designed to identify two phytoplankton species that are well-known to cause harmful blooms: Karenia mikimotoi and Chattonella antiqua. The instrument takes advantage of the Eluorescence spectral Shift Index (FSI)* of these two species that is relatively high when compared to other species.
*Eluorescence spectral Shift Index (FSl) is the ration of fluorescence intensity at 690 nm to that at 670 nm in wavelength.
