Smart Water Management in Agriculture Using IoT and Soil Moisture Sensors

Abstract

Advances in the Internet of Things (IoT) are helping to make water management smarter and optimizing consumption in the smart agriculture industry. Efficient water management is a critical challenge in modern agriculture due to increasing water scarcity and the inefficiency of conventional irrigation practices. This paper presents a Smart Water Management System for agriculture using the Internet of Things (IoT) and soil moisture sensors, aimed at optimizing irrigation by delivering water based on real-time soil conditions. The proposed system integrates soil moisture sensors with a microcontroller and wireless communication module to continuously monitor soil moisture levels and transmit data to a cloud-based IoT platform. Based on predefined threshold values, the system automatically controls irrigation through actuators such as water pumps or solenoid valves, thereby minimizing human intervention. Real-time monitoring and remote access are enabled through a web or mobile application, allowing farmers to make informed decisions. Experimental results demonstrate that the proposed system significantly reduces water consumption while maintaining optimal soil moisture levels for crop growth. The system offers a low-cost, scalable, and energy-efficient solution that enhances water-use efficiency and supports sustainable agricultural practices.
