I. INTRODUCTION

Hydroponics, a soilless agriculture method utilizing nutrient-rich water, presents a sustainable solution amidst climate change concerns and environmental degradation linked to intensive farming. This innovative approach offers advantages such as minimized water usage, reduced land footprint, and elimination of pesticide requirements. Its potential for vertical farming makes it particularly suitable for urban settings, where space is limited and population density high. Furthermore, hydroponics aligns with the goal of self-sustaining urban food systems, alleviating pressure on remote farms, decreasing habitat disruption, and curbing carbon emissions associated with transportation. Despite its promise, widespread adoption remains hindered by cost barriers, especially for small-scale farmers. To address these challenges and leverage the benefits of hydroponics, this project proposes the integration of Internet of Things (IoT) technology into multilayer hydroponic farming. By incorporating IoT, farmers gain the ability to remotely monitor and control crucial environmental variables like temperature, humidity, and nutrient levels, leading to enhanced efficiency, increased yields, and minimized resource wastage. Additionally, IoT facilitates automation, real-time data analysis, and predictive maintenance, revolutionizing traditional farming practices and promoting sustainable agriculture. The objectives of this project encompass several key aspects.
