Green oasis: A personalized indoor plant recommendation engine

Introduction

Indoor plants are more than just decorative elements-they can purify the air, boost productivity, and contribute to overall well-being. However, with so many different plant varieties available, it's not always clear which one suits a particular indoor space. Factors like sunlight, temperature, and humidity significantly affect a plant's success in a room. The goal of this project is to develop a user-friendly application that provides personalized plant recommendations. The system uses information from users, such as their room's lighting and climate conditions, and their preferences for plant care. By doing so, it helps users select plants that will thrive in their spaces, ensuring longterm success for both the plants and the human caregivers. Indoor plants have become a staple in modern homes, not only for their beauty but also for the well-documented health benefits they offer, such as improved air quality and reduced stress levels. However, the process of selecting the right plant for a particular indoor setting is far from straightforward. Each room presents its own set of challenges-varying light levels, humidity, temperature, and space constraints can all affect a plant's ability to thrive. Recognizing this challenge, our project aims to create an application that makes the process of choosing an indoor plant both personalized and hassle-free. This application works by analyzing the specific conditions of a user's space and aligning those with the unique care requirements and growth patterns of various plants. It considers factors like natural light exposure, the amount of maintenance a plant needs, and even the user's aesthetic preferences, ensuring that the recommended plant isn't just a good fit for the room, but also for the lifestyle of the person living there. By taking a data-driven approach, our system goes beyond generic suggestions, offering tailored advice that adapts to diverse living environments. Moreover, this project addresses the growing trend of smart home technologies by integrating an intuitive interface with a robust recommendation engine. As indoor gardening continues to gain popularity, especially among urban dwellers with limited green space, this application stands out as a practical tool designed to help people create healthier, more inviting homes.

[15] propose a holistic system that merges automated sensor data, real-time user feedback, and expert horticultural insights. Their framework not only recommends suitable plants based on current indoor conditions but also offers ongoing care instructions, helping users maintain healthy plant environments over the long term. The methodology begins at the User Interface, where individuals access the application-often via a web or mobile platform-and provide information about their indoor environment. This step allows users to specify details like room size, lighting conditions, temperature, and any specific preferences, such as wanting low-maintenance plants or options safe for pets. Once the User Input is collected, the system moves into Data Collection & Processing. Here, user-submitted details are validated, normalized, and prepared for further analysis. Any missing information might be estimated based on default values or prompt the user for additional input. This stage ensures that the application handles data in a consistent, structured manner. The processed data then feeds into the Recommendation Engine, which applies rule-based logic or machine learning techniques to match the user's environment and preferences with suitable plant options. To achieve this, the engine consults a Plant Database containing essential information on each plant's ideal growing conditions, care requirements, and unique attributes. By comparing these plant profiles against the user's data, the system narrows down the list to the most compatible choices. Next, the refined information is sent to the Recommendation Engine, which uses a combination of rule-based logic and potentially machine learning algorithms to match the user's environment with the optimal plant profiles. These plant profiles reside in the Plant Database, a resource that contains detailed attributes for each plant, such as ideal light conditions, watering schedules, and growth habits. Finally, the application consolidates the engine's results into a concise list of recommendations and delivers them as the Output to User. Alongside the plant suggestions, users also receive care guidelines tailored to their chosen plants, helping them maintain a healthy and vibrant indoor garden. The process begins when the user accesses the application. The system initializes and loads the necessary resources, including the plant database. The user provides details about the indoor environment, such as light availability (low, medium, high), humidity levels, temperature range, and purpose (air purification, decoration, pet-friendly, etc.). This input is essential for filtering plants that thrive under specific conditions. Once the user inputs the required data, the system processes it by matching the conditions with the plant database. The database contains predefined information about various indoor plants, including their ideal growing conditions and care requirements. Based on the processed data, the system selects suitable plants that match the given conditions. It applies a filtering mechanism to shortlist the best plant options for the user. The application displays the recommended plants along with descriptions, benefits, and care instructions. The user can review the recommendations and select a plant that fits their preference. The process concludes here unless the user wants to modify their input and receive new recommendations.
