The new multi-spectral water quality analyzer based on MSP430

In the aquaculture industry, the content of ammonia and nitrite in water has a big effect on aquaculture organisms. In this study, the authors adopted with the spectrum information fusion theory as the core, then designed a new water analyzer which based on spectral analysis of the water body compounds determination. The water quality analyzer can automatically complete the whole detection process concluding measurement, display, storage by anglicizing a small amount of water-like samples. The instrument is able to quickly detect the content of ammonia nitrogen and nitrite. The actual measurement results show that the testing equipment simple structure, little error, measurement precision, and some innovation technology, so it can be widely used in aquaculture, and also applies to domestic sewage and automatic detection of the lake surface water.
