Integration of Frequency Control and Water Quality Monitoring System Into Fish Caller Device Based on IoT

– Seawater pollution is highly detrimental to human life and marine biota. Quality of seawater in a particular location also affects fish caught by fishermen. This is the reason why early detection of water conditions is crucial for the preservation of the marine ecosystem with a focus on the measurements of temperature, pH, and salinity. Separate researches have been conducted on the application of sensors and IoT to measure seawater quality as well as fish caller device to increase the possibility of catching fish. Therefore, this research has been used to integrate both devices in order to ensure fishermen contribute to the provision of information on seawater quality while catching fish by using fish caller device. This has been achieved through the implementation of NodeMCU ESP8266 to control frequency of fish caller device as well as to assess the parameters of seawater quality. Moreover, data obtained from the sensors have been first stored in a microSD card in order to overcome the lack of internet connectivity at the location and automatically sent to the server once the NodeMCU established an internet connection. An Android smartphone application has been used to select frequency of fish caller device according to the desired fish species as well as to view the seawater quality data stored on the server. This effort is directed at ensuring that an integrated system is developed to increase frequency of catching fish using fish caller device while contributing to the process of monitoring seawater quality, which is crucial for the preservation of the marine ecosystem.
