Nutrient Film Technique for Automatic Hydroponic System Based on Arduino

Abstract

Hydroponic Nutrient Film Technique (NFT) system is a method of cultivating plants with plant roots growing in shallow and circulating hydroponic nutrient layers so that plants can get enough water, nutrients, and oxygen. Plants grow in layers of polyethylene with plant roots submerged in water containing nutrient solutions that are circulated continuously with a pump. Arduino is used as a microcontroller that regulates the composition of solutions containing nutrients to be circulated with a pump by the NFT system Hydroponics. A tool that can regulate the circulation of nutrients for the NFT system automatically.
