The researchers focused on improving crop growth in greenhouses by studying the key factors that affect the environment inside. They found that temperature, soil moisture, humidity, and lighting are crucial elements that influence plant growth. To help maintain these conditions automatically, they developed a system that can measure and adjust these parameters as needed. This system works by monitoring the environment and making changes to keep the conditions just right for the plants. Overall, the study outlines a practical way to create a system that can regulate the greenhouse environment to help crops grow better.
