This project introduces a Smart Irrigation System aimed at enhancing water efficiency in agriculture through the integration of an Arduino Uno micro-controller and a variety of sensors. The system incorporates a soil moisture sensor, a DHT11 sensor for monitoring temperature and humidity, an LCD, a buzzer for alerts, and a relay module to control a pump motor. The main goal is to create an automated irrigation system that adjusts to environmental conditions, thereby optimizing water usage for plant growth. The soil moisture sensor continuously evaluates soil moisture levels, while the DHT11 sensor keeps tabs on temperature and humidity. The Arduino Uno processes this data and displays it on an LCD screen. When the soil moisture falls below a predefined threshold, the system activates a buzzer and triggers the relay to turn on the pump motor. The LCD provides real-time feedback on environmental conditions and the irrigation status. This Smart Irrigation System offers several advantages, including water conservation, energy efficiency, and improved plant health. By automating irrigation based on real sensor data, the system minimizes water wastage and ensures that plants receive optimal moisture levels. Additionally, temperature and humidity monitoring contribute to effective microenvironment management. The project serves as a demonstration of IoT-based solutions for agricultural challenges, featuring a modular design that allows for scalability. Future developments may include incorporating additional sensors, enabling wireless connectivity for remote monitoring, and integration with weather data. In summary, the system provides a practical and cost-effective solution for sustainable agriculture, promoting water conservation and efficient farming practices.
