About this project

Abstract

The Hydropod project represents a significant advancement in agricultural technology through the application of Internet of Things (IoT) principles, artificial intelligence (AI), and machine learning (ML). The aim of the project was to develop an automated vertical hydroponics system capable of optimizing plant growth conditions, automating routine tasks, and facilitating real-time monitoring and problem detection. After a successful three-month growth period of various lettuce species within a controlled environment, the system significantly outperformed traditional growing methods, showcasing both its efficiency and enormous potential for commercial and residential applications.
