The article talks about creating a system for controlling a greenhouse efficiently using modern technology like Internet of Things (IoT). Their goal was to ensure the greenhouse conditions are perfect for plant growth while using minimal energy. They built a small model greenhouse with plants and a smart controller with a touchscreen. This controller allows users to monitor and adjust the greenhouse environment remotely. The important data about the greenhouse conditions is also sent to the cloud for easy access and analysis. The research resulted in a system that can maintain optimal conditions in the greenhouse, helping plants grow better and saving energy.
