A smart irrigation system using IoT works by continuously monitoring field conditions like soil moisture, temperature, and humidity. When the soil gets too dry, the system sends a signal to activate irrigation automatically. If rainfall is expected, it delays watering. All data is sent to a cloud dashboard for monitoring and control. Farmers can access this information from their smartphones, making real-time decisions easier and more efficient.
