This paper presents the design and implementation of an aquaponics greenhouse cloud-based wireless monitoring system and control that allow plants and fish to co-exist in a synergetic and controlled ecology. Two controllers are designed based on threshold values for effective nitrification and mineralization processes, as well as to enhance the rate of photosynthesis. As compared to our previous work, Wi-Fi technology and cloud data storage are utilized instead of GSM to reduce the cost in monitoring and increase accessibility of the aquaponics greenhouse parameters to many users. Modification in the design of the solar energy conversion system is done with higher ratings on solar panels and batteries to ensure an uninterrupted power. The experimental data gathered during summer and winter days in an arid region show the performance of the designed aquaponics greenhouse system in promoting sustainability. Current developments in the design and implementation of an aquaponics greenhouse system as well as possible improvements for large-scale production set-up are also discussed in the paper.
