The invention discloses an aquaculture pond dissolved oxygen detection device. The device is characterized in that a detection system is composed of two parts including an aquaculture pond environmentwater quality parameter acquisition platform based on a wireless sensor network, and a pond dissolved oxygen intelligent early warning system. The device provided by the invention effectively solvesa problem of great influence on aquaculture pond dissolved oxygen detection caused by lack of detecting the dissolved oxygen of the existing aquaculture pond according to the characteristics, such asnonlinearity and great lag of change of pound dissolved oxygen and large area and complex change of dissolved oxygen of the aquaculture pond.
