Abstract
Irrigation consumes 70% of the water quantity used worldwide. In a context of rising food demand and declining in water resources, the development of advanced irrigation technologies based on modern techniques in agriculture is a significant demand to keep this resource safe. To achieve this target, the management of water resources in agriculture needs to be specified and controlled. This study aims to propose an automatic, non-contact and cost-effective soil irrigation system based on analysing the changes in loam soil colour captured by a digital camera at different illumination levels. A graphic user interface (GUI) attached to the Arduino Uno microcontroller was used to drive the water pump and determine whether the loam soil requires irrigation or not. The experimental results illustrate the effectiveness of the proposed irrigation system to determine soil state and provide an accurate decision for soil irrigating, thus making this system a promising approach in future irrigation technologies.
