Automated Hydroponics for Agricultural Applications

Abstract

Food shortages and population expansion are some major issues faced in recent times. As a result, many countries struggle to provide food for their citizens. This is mostly due to the fact that food production does not expand in proportion to the growing population. Some of the causes for this are a lack of available land space, pollution, climate change, and so on. In this scenario, hydroponics is a much-preferred alternative for agriculture. It does not need soil for agriculture but uses water as a medium to grow crops. Smart farming technologies help farms more intelligently perceive their vital components. A hydroponics system may be used to raise vegetables and other nutritious crops. But various parameters like pH, nutrient level, and temperature must be strictly monitored and maintained for the healthy growth of crops. Nutrient mixing is a crucial system component that directly affects plant development. With the use of specialized sensors, the IoT-based hydroponics monitoring system has the ability to track pH value, temperature, humidity level, and water level. After those values have been obtained, they are displayed on a liquid crystal display and a mobile application via the Internet of Things. The recommended automated solution would do away with the drawbacks of the existing approach. Long-term data gathering may improve accurate reckoning. Many Sustainable Development Goals (SDGs) are met by this initiative, including eradicating hunger and poverty and creating sustainable towns and cities.
