It should be known that different kinds of fish live in the same PH water environment, and their development degree, growth cycle and health degree are different, so the water PH value should be monitored and regulated strictly in accordance with the growth environment of different kinds of fish. Today, with the development of science and technology, most fish pond farms are using online PH sensors to monitor the PH value of fish ponds. Dissolved oxygen is also the case, the dissolved oxygen value in water is too large or too small will lead to fish pond is not suitable for fish farming, so dissolved oxygen is also needed to use dissolved oxygen detector for parameter monitoring and control.
With the rapid development of Internet of Things technology, intelligent and automated aquaculture has become a development trend of large-scale aquaculture in the future. Collect water quality monitoring data in aquaculture farms through water quality sensors, such as the use of dissolved oxygen analyzer to monitor the dissolved oxygen content in water, and then managers improve aquaculture measures according to the data monitoring data to increase the income of aquaculture.
