IoT-based Coastal Fisheries Monitoring System

Coastal fisheries activities play an important role in contributing to economic development, especially for countries that have a wide coastline. Among the coastal fisheries activities that are commonly practiced by the locals is the farming of fish, shrimp, and various other marine life in cages. However, this activity is exposed to natural risks such as marine heat wave, high pH and red tide. In addition, water pollution caused by daily human activities such as tourism and industry also affect coastal fisheries activities. To ensure sustainable and quality seafood, innovation in the field of information technology can be utilised. This technical paper explains the development of a coastal seawater monitoring and data logging system for use by fishers. The data observed by this system are temperature, pressure, air humidity, wind speed, water pH and environmental images using several sensors controlled by NodeMCU ESP8266 and Arduino. The system is deployed on a few buoys located within a range of 10 to 50 meters from the cage breeding area in the coastal region. Its purpose is to identify the occurrence of maritime hazards, such as heat waves and red tides, at an earlier stage. The control system on the buoy that uses battery and solar energy sends the data observed by the sensor using the 4G telecommunication network signal to be stored in cloud storage. Farmers can access water quality information around their cage breeding areas in real-time by using mobile phones and personal computers that are installed with an interface application developed using the Arduino IDE software and Blynk platform. This technology that uses IoT can help coastal farmers to take early action that can reduce the risk of losses due to some natural phenomenon.
