## Overview

This ESP32 project automates irrigation using soil moisture and rain detection, with pump control and water-flow measurement; it also exposes readings and controls through Blynk and retrieves weather information from OpenWeather. The tree contains one sketch, so runtime responsibilities share its path. No source excerpts were available; relationships shown are limited to those stated in the README.

Main entry points: [`IrrigationSystem_Final.ino`](https://github.com/nikhilsp780/-smart-irrigation-system-esp32/blob/main/IrrigationSystem_Final.ino) (Sensor Monitoring)
