Abstract: Agriculture faces major challenges such as inefficient water usage, unpredictable weather conditions, and the need for continuous field monitoring. To address these issues, this paper presents an IoT-based Smart Agriculture System using ESP32, designed for real-time monitoring and automated irrigation. The proposed system integrates soil moisture, temperature and humidity, rain, and water level sensors with an ESP32 microcontroller to continuously collect environmental and soil parameters. Based on the sensed data, the system automatically controls the irrigation unit, ensuring optimal water supply to crops while avoiding over-irrigation, especially during rainfall conditions. The ESP32’s built-in Wi-Fi enables seamless data transmission to the internet, allowing farmers to remotely monitor field conditions through a mobile or web application. To enhance sustainability and reduce dependency on conventional power sources, the system is powered using a solar panel, making it suitable for rural and off-grid agricultural areas. Overall, the proposed system improves crop productivity, conserves water resources, reduces manual labor, and supports smart and sustainable agricultural practices through efficient IoT integration.

Keywords: IoT, Smart Agriculture, ESP32, Automated Irrigation, Soil Moisture Sensor.
