Internet of Things for Monitoring and Controlling Nutrient Film Technique (NFT) Aquaponic

Abstract

Aquaponic NFT system is a merging system between hydroponic NFT and aquaculture. The NFT Aquaponic system needs circulation of water for 24 hours. Thus, It needs to monitor and control the level of ammonia, temperature, pH, and nutrients continuously for maintaining the environment of NFT Aquaponics. The common aquaponic system doesn’t control their environments. The proposed system in this paper is using the internet of things (IoT) for monitoring and controlling the NFT Aquaponic environment. Smartphone mobile application is developed for controlling and monitoring the environment of NFT Aquaponic. This application maintains the nutrition and stabilizes the water condition. The proposed system absorbs more nutrients through a nitrification process. The plants grow better compared with uncontrolled systems. some experiment has been done to investigate the plant growing, it is shown that controlled NFT Aquaponic produces better vegetables compared with NFT Hydroponic in terms of a height of plants, a number of the leaf and the weight of a plant.
