An irrigation controller is a device used to automate and regulate the irrigation process in agricultural fields. It plays a crucial role in ensuring that crops receive the right amount of water at the right time, optimizing water use efficiency and enhancing crop yield. The irrigation controller achieves field irrigation through several key mechanisms and features.


One of the primary functions of an irrigation controller
is to schedule irrigation events based on specific parameters and requirements. Farmers can program the controller with information such as crop type, soil type, and weather conditions. Using this data, the controller determines when and how much water should be applied to the field. The scheduling feature takes into account factors such as evapotranspiration rates, soil moisture levels, and water requirements of the crops. By automating the scheduling process, the irrigation controller eliminates the need for manual monitoring and decision-making, saving time and reducing the risk of human error.
