Ceilão.Grid is a smart Android-based mobile application developed to revolutionize small-scale gardening and promote sustainable agriculture in Sri Lanka. The core idea is to empower individuals—especially urban dwellers and small-scale farmers—to grow their own food effectively, even in limited spaces, while reducing reliance on chemically grown commercial produce. The app leverages advanced technologies like Augmented Reality (AR), Artificial Intelligence (AI), and real-time weather APIs to deliver a personalized and practical gardening experience. Using AR, Ceilão.Grid allows users to scan and measure their available land accurately, offering optimal layout plans for planting. Based on the scanned data, location, and soil type, the app recommends suitable crops and intercropping methods. It also provides cost estimations, revenue predictions, watering schedules based on weather forecasts, and guidance on pest control using an AI chatbot. Furthermore, with offline accessibility and a simple UI, Ceilão.Grid is designed to be inclusive and user-friendly for a wide audience. The app’s modular design, developed using Kotlin and Node.js, ensures maintainability and scalability. Ceilão.Grid isn't just a gardening tool—it's a lifestyle companion that encourages eco-conscious living, community development, and food independence. It addresses real-world problems with a blend of technology and empathy, making sustainable gardening achievable for all.
