Smart Soil-Driven Irrigation Control System Using Arduinoย 

Overview:ย 

This is a Microprocessor-based Smart Irrigation System developed using Arduino Uno. The system is designed to automatically monitor soil moisture levels and control a water pump based on real-time environmental conditions.

A soil moisture sensor continuously measures the moisture level of the soil, and the Arduino processes this data to decide whether irrigation is needed. When the soil becomes dry beyond a set threshold, the system automatically turns ON the motor (water pump), and when sufficient moisture is detected, it turns OFF the motor to prevent over-watering.

The system also includes a crop selection feature (Rice and Maize), allowing different moisture threshold values depending on the crop type. A push button is used to switch between crop modes.

An LCD display shows real-time information such as crop type, soil moisture percentage, and motor status (ON/OFF), making the system user-friendly and easy to monitor.

LED indicators are used to visually show system status, improving usability and quick understanding of irrigation conditions.

This project demonstrates the practical use of microcontrollers in smart agriculture, helping to improve water efficiency and automate farming processes.
