Sensors for water levels, rainfall, temperature, and soil moisture track real-time environmental parameters. Temperature readings ranged from 25°C to 31°C over the 8-day research, but soil moisture was continuously kept within ideal ranges. Water waste was reduced and timely refills were ensured by the water tank level sensor mechanism, which successfully maintained a threshold of 15 cm. Based on sensor data, intelligent algorithms control irrigation, minimize waterlogging, and maximize water usage. Convenience and operational efficiency are increased via remote management via the Blynk app. This intelligent irrigation system provides a sustainable and effective answer to contemporary agriculture by preserving water, improving crop health, and facilitating data- driven farming methods.
