Smart Aerial Spraying System : An IoT-Integrated Quadcopter For Sustainable Farming

The growing demand for sustainable agricultural practices calls for innovative technologies that enhance productivity while reducing environmental impact. This study introduces a Smart Aerial Spraying System, an IoT-enabled quadcopter developed to support precision farming operations. The system integrates unmanned aerial vehicle (UAV) technology with real-time sensing and cloud-based monitoring to deliver accurate and efficient pesticide and fertilizer application. Embedded sensors collect data on temperature, humidity, soil moisture, and crop conditions, enabling adaptive spray control based on field requirements. Through IoT connectivity, farmers can remotely supervise flight operations and spraying parameters using a mobile or web dashboard. GPS-guided navigation and automated route planning ensure uniform coverage and operational safety. The proposed solution reduces chemical overuse, lowers labor dependency, and minimizes human exposure to hazardous substances. Experimental results indicate enhanced spraying accuracy, better resource utilization, and improved efficiency compared to traditional manual methods, highlighting its potential as a reliable tool for sustainable and intelligent agriculture.
