Abstract: The flourish of Internet of Things (IoT) is leveraging the reform of today’s agriculture, including the development of new intelligent irrigation systems for the management of water resources. The integration of analytics-informed weather information in IoT-enabled irrigation systems enhancing accuracy, sustainability, and farm-level efficiency is examined in the current work. Traditional irrigation methods may rely on rigid schedules or manual manipulation that result in waste, lack of uniformity in the irrigation area, or in an inability to obtain the desired crop yield at the correct time of the year, particularly in areas with variable precipitation.
To overcome these limitations ,the system proposed here leverages a comprehensive network of IoT devices—including soil moisture sensors, temperature and humidity monitors, rain gauges, and weather stations—to gather live environmental data. This information is transmitted using communication protocols such as LoRaWAN, Wi-Fi, or NB-IoT to a centralized cloud environment. There, predictive models and machine learning algorithms analyze weather indicators like rainfall predictions and evapotranspiration rates, cross-referencing them with soil data to inform irrigation needs in real time.
Field evaluations revealed that the smart system cut water usage by 30–40% compared to traditional practices and boosted crop yields by 15–20% by maintaining optimal soil hydration. A user-friendly interface also gives farmers real-time oversight and the flexibility to intervene manually when needed. By combining IoT connectivity, multi-source data integration, and adaptive automation, the system helps farmers navigate extreme weather events such as droughts and sudden rainfall. Its affordable components and scalable design make it suitable for farms of all sizes.
Ultimately, this research highlights how IoT-powered weather analytics can drive more sustainable water use in agriculture, lower operational costs, and contribute meaningfully to global food security. It calls for greater adoption of smart irrigation systems that align agricultural productivity with environmental stewardship.
