The old-fashioned way of farming is no longer relevant. It takes a lot of time to complete. Researchers are putting a lot of effort into finding innovative ways to cultivate plants and boost yields. When compared to conventional farming methods, hydroponics farming is thought to yield higher yields. Population growth necessitates prioritizing increased productivity without sacrificing nutritional value. In India, onions are regarded as the most important and widely consumed crop. Onions grown hydroponically yield more and have higher nutrient values. With an Internet of Things system, onion growth in hydroponics can be tracked. Sensors and microcontrollers can be used to automate the system, implying inter machine communication and hydroponics system manage. The hydroponic system control action can be provided by the intelligent system based on multiple parameters. In this Internet of Things (IoT)-based hydroponics system, the cost of electricity can be decreased and it is also environmentally friendly by with the solar provide to regulate irrigate run. Whenever the plant requires the solution, the system will release it automatically. © 2024 Elsevier B.V., All rights reserved.
