Development of Sustainable Hydroponics Technique for Urban Agrobusiness

G. Swaminathan, G. Saurav


In this work develop a system that uses a combination of advancements in fuel cell technology, solar power, and hydroponics. The developed system effectively distributed in the agricultural sector, resulting in a drastic increase in urban farming and the enhancement of traditional rural farming methodologies. Hydroponic farming is a technique by which the crops are grown without soil, it benefits the environmental by eliminating erosion and water consumption by the crops, it also reduces the labor-intensive work involved in traditional framing technique. The introduction of automation in this hydroponic system and improve the monitoring of the consistency of the yield. The implementation of fuel cell technology and solar panels aids in reducing the carbon footprint of the system. As good as it sounds in efficiency and protecting the environment, it is challenging to get the right and ambient conditions for the plants to grow. Water and nutrients must be provided in a required ratio while being constantly monitored with the help of an array of sensors calibrated and coded with Raspberry Pi. The automated system helps us to maintain optimal conditions for plant growth. The primary power supply is provided by a fuel cell or even magnesium salt water fuel cell. which uses an anion exchange membrane to generate electricity to power the automation equipment for the hydroponics system. The function of solar cell is used to facilitate the fuel cell to generate hydrogen which then circulated to the fuel cell. This potentially replaces the need for setting up of massive external power source for electrolysis.
