A good irrigation system is an irrigation system that is in accordance with the labor on the plant itself. So a system such as a smart irigation system is designed that can regulate and monitor the irrigation system automatically. With sensors that can identify humidity and water levels so that they can provide appropriate needs to plants. The method that will be used is the Decision Tree classification method, which will help the system in terms of data processing and classification. Which is expected to get accurate and better results.
