Monitoring River Pollution of Marine Environment

The purpose of this paper is to monitor river environmental data with various water quality sensors to provide relevant management units and deal with river pollution urgently to save marine ecology. Figure 1 shows the major incidents of river pollution from 2012 to 2020. If the pollution of the river can be known in advance, the degree of pollution in the coastal waters can be greatly reduced. In the paper, a water quality sensor combined with a 4G/5G module was used to send the detected data to the server. On the server, the received water quality detection data is compared with the conversion tables of various conductivity values of heavy metal to determine whether the water quality is abnormal.
