Development of Environmental Monitoring System for Aquaculture Application

Abstract

Good quality of water is important for maintaining the quality of the aquaculture. The water quality index can be improved using a real-time monitoring system for analysis, monitoring, and observation. Sungai Pahang is known as the largest river in Malaysia and contributes in freshwater aquaculture industry. The habitat of aquaculture can be affected in term of environmental, water quality and parasite. Mostly the pollution factor is from bauxite, deforestation, and due to dry and flood season. This paper aims for observation of the environmental factors in term of turbidity, total dissolved solid and temperature using wireless sensor network. Higher percentage of the dissolved solid and turbidity in the waters could decrease the percentage of oxygen. The sensors used are temperature sensor, turbidity sensor and total dissolved solid sensor for collecting the data. The project used LoRa Dragino LG01-S gateway for transmitting the data based on real-time monitoring. By using Arduino as microcontroller, the sensors collect the data and transmit the data through LoRa nodes to be displayed in FRED application. The result revealed the characteristic of turbidity, total dissolved solid and temperature for 3 different scenario of river, puyu pond and catfish pond. Thus, this research is expected to realize the advantage of monitoring the environment not only for aquaculture but also for human and other living thing. The low strength of LoRa WAN communication is expected due to the suburban area. However, the signal strength could be improved using more sensor nodes as medium of transmission.
