Abstract. A method to minimize and monitor water and energy consumption in agriculture and landscaping lies in using smart automated sprinkler irrigation systems. This paper presents a complete simulation of a smart irrigation design for efficient water use and optimal soil quality. The proposed system utilizes an ATmega32 AVR microcontroller, along with soil moisture, temperature, gas, and humidity sensors, a Pulse Width Modulation (PWM) control of water pumps and valves. It is automated to regulate irrigation intensity with a closed-loop control enhanced by a PID controller and a lightweight artificial intelligence-inspired decision layer using rainfall data of the region of Fes-Meknes-Ifrane for threshold adjustments. The results highlight the improvement of soil moisture stability in the range of 4%, as well as a respective mean absolute error and a root mean square error of 3.5% and 5% compared to a threshold sensing method only.
