Abstract: The growing necessity for water conservation in agriculture has led to the development of advanced irrigation systems that enhance water efficiency while promoting robust crop growth. This initiative outlines the design and implementation of an IoT-based Smart Irrigation System aimed at effective water management, specifically designed for onion cultivation. The system incorporates an ESP8266 (NodeMCU) microcontroller, along with a soil moisture sensor, rain sensor, DHT11 temperature and humidity sensor, a relay-operated water pump, and a real-time monitoring and control interface through the Blynk mobile application. The soil moisture sensor continuously tracks the water content in the soil, the rain sensor detects rainfall, and the DHT11 records temperature and humidity levels. Utilizing feedback from these sensors, the system automatically controls the water pump via the relay module to maintain ideal soil moisture levels. Additionally, users can oversee environmental conditions and manually adjust the irrigation system through the Blynk app, thereby enhancing user flexibility and management efficiency. By automating irrigation processes and facilitating remote monitoring, the proposed system reduces excessive water usage, minimizes the need for human intervention, and improves crop vitality. This intelligent irrigation solution not only promotes sustainable agricultural practices but also utilizes affordable, readily accessible IoT components, making it suitable for small to medium-sized farming operations.
