An automated solar-powered aquaponics system towards agricultural sustainability in the Sultanate of Oman

Abstract

This paper introduces an automated solar-powered aquaponics system, designed and implemented to be cost-effective and environmentally sound for local communities in Oman and other arid regions. It presents the design, construction and implementation of the following modules: 1) water recirculation system that circulates water to an aquaculture tank and hydroponic beds; 2) aquaponics control and monitoring system using Arduino microcontroller interfaced with sensors, actuators, GSM shield and NI LabVIEW that allows plants and fish to grow together in an interdependent and controlled environment; 3) solar energy conversion system that powers the whole project using the concept of renewable energy source; and, 4) cooling and heating systems that maintain the air and water temperatures to acceptable level for plant and fish growth. The analyses of experimental data taken during summer and winter time show the sustainability of the designed aquaponics system.
