Real-Time Monitoring

Project Overview Global freshwater scarcity is a pressing challenge for sustainable development, with agriculture consuming over 70% of the world’s freshwater resources—much of which is wasted due to inefficient irrigation methods. In parallel, modern lifestyles have increased the demand for remote plant care solutions. To address these challenges, I developed an intelligent, fully automatic flowerpot system that integrates cutting-edge technologies such as micropumps, intelligent sensors, IoT cloud platforms, and AI-powered large language models. This system ensures precise control of plant care, providing the ideal environment for growth while significantly reducing water waste. Why We Do This Project: Tackle Global Water Scarcity: Freshwater demand continues to rise, especially in agriculture, which is the largest consumer. This project aims to create a water-efficient solution to reduce waste and optimize resource use. Enhance Agricultural Sustainability: Traditional irrigation methods are often wasteful and lack precision. By enabling accurate, need-based water and nutrient control, this project promotes more sustainable farming practices. Accommodate Busy Lifestyles: With increasingly hectic schedules and frequent travel, people often find it difficult to care for plants consistently. This automated planter ensures reliable plant maintenance even when users are unavailable. Support Plant Enthusiasts and Beginners: Caring for plants, particularly exotic or sensitive species, can be challenging for inexperienced growers. The system provides smart recommendations and automation to simplify plant care. Drive Technological Advancement: By combining AI, IoT, and sensor technologies, this project demonstrates how cutting-edge innovations can address practical challenges and contribute to the development of smart agriculture. 1.
