IoT Based Smart Irrigation System Using ESP32

Efficient water management is a critical requirement in modern agriculture due to increasing water scarcity and the need for sustainable farming practices. Traditional irrigation systems rely on manual operation and fixed schedules, which often result in over-irrigation, water wastage, and reduced crop productivity. This paper presents an IoT-Based Smart Irrigation System using ESP32, designed to automate irrigation based on real-time environmental conditions. The system utilizes a soil moisture sensor, temperature sensor, and water level sensor to continuously monitor field parameters. The ESP32 microcontroller processes the sensor data and controls a water pump through a relay module, ensuring that water is supplied only when required. The proposed system also incorporates IoT technology to enable wireless monitoring and control through a mobile or web interface. This allows users to access real-time data and manage irrigation remotely. The system is low-cost, energy-efficient, and easy to implement, making it suitable for small-scale farms, gardens, and greenhouse applications. The results demonstrate that the system effectively reduces water wastage, minimizes human intervention, and improves irrigation efficiency, thereby contributing to smart and sustainable agricultural practices.
