Design and Implementation of an IoT-Based Indoor Hydroponics Farm with Automated Climate and Light Control

With the boom of industrialization and the escalation of world population, there is a significant decline in the land suitable for farming and an increase in demand for food. Hydroponics, a branch of agriculture, facilitates the growth of plants in water without the use of soil. This offers a lifeline of sorts by making vertical farming possible. Hydroponics gives us the freedom to wholly control the parameters that affect plant growth, and if done correctly, it can be beneficial both commercially and environmentally. Manual monitoring of all the variables of plant growth is difficult and can lead to growth failures. This paper proposes how the Internet of Things (IoT), a revolutionary technology can be integrated with hydroponics to automate the process of climate monitoring and control. A practical model is implemented in this paper where IoT sensors are used to control the climate conditions and ambient lights of the hydroponic farm. Sensors monitor the climate and light conditions throughout the day and automatically maintain suitable growth conditions.
