In the field of aquaculture, used pesticides and fertilizers can flow into aquaculture areas, bad influence is caused on water quality, aquatic products are reduced in yield and even die, and economic loss of farmers is directly caused. Therefore, in order to ensure the water quality safety of aquaculture and improve the yield and quality of aquatic products, the water quality of an aquaculture area must be monitored, so that farmers can more accurately acquire water quality data and make corresponding decisions according to water quality changes to carry out more scientific and healthy aquaculture.
At present, the method for monitoring water quality mainly comprises the steps of establishing a monitoring station in a key water area, automatically or remotely controlling to sample and analyze the water quality, and transmitting water quality parameters to a remote monitoring center. The method is suitable for large rivers, has high manufacturing cost and difficult point distribution, can be used for monitoring only at fixed sites, needs to establish a plurality of sites if the water quality needs to be monitored in all directions, and is not suitable for small culture water areas. In addition, the method is a laboratory instrument measuring method, water quality needs to be sampled manually on site, the water quality is sent back to a laboratory, and a professional instrument is used for analyzing water quality parameters. Aiming at a mobile water quality monitoring method, the monitoring instruments at home and abroad have huge volume and single function.
