Smart Irrigation System Using Arduino and LabVIEW for Real-Time Monitoring and Efficient Water Management

Abstract

Efficient water management is a critical challenge in agriculture, particularly in regions experiencing water scarcity and climate variability. Conventional irrigation systems, typically based on fixed schedules or manual practices, often result in over- irrigation or under-irrigation, leading to resource wastage and reduced crop performance. This paper presents the design and implementation of a Smart Irrigation System that integrates Arduino-based embedded hardware with a LabVIEW graphical interface to achieve real-time monitoring, automation, and user-driven control of irrigation. The system continuously measures soil moisture, temperature, and humidity, enabling dynamic threshold-based irrigation supported by a manual override option. Experimental validation confirmed that the system operates reliably, responds accurately to changing soil conditions, and prevents unnecessary irrigation by activating the water pump only when required. Unlike existing solutions, the proposed system provides dual operating modes, interactive threshold adjustment, and intuitive real-time visualization through LabVIEW, making it both scalable and cost-effective for small- to medium-scale farming applications. This work contributes to sustainable agricultural practices by combining affordability, adaptability, and improved water-use efficiency.
