Dissolved oxygen (DO) in water is a key parameter, which represents the purification capacity of water and also creates conditions for the survival of aquatic organisms. Among the existing DO detection methods, most of them adopt on-site sampling and laboratory detection, or arrange sensor network for fixed-point detection, or adopt buoy method for detection. These detection methods are either not precise or accurate enough, or it is difficult to reflect the water quality in real time. It is difficult to meet the current high requirements for water quality testing. This paper proposes the idea of using bionic robotic fish carrying water quality sensor system to realize multi-parameter detection of water quality, which not only gives full play to the advantages of optical sensor detection in accuracy and accuracy, but also gives full play to the good adaptability of fish in water. In this study, a fluorescence dissolved oxygen sensor was used to detect DO in situ. The automatic location of pollution source can be realized on this basis. This research can provide an idea for the detection and research of submarine archaeology and deep-sea mineral exploration, especially underwater in-situ detection.
