Once the defuzzification process has been carried out, the following preliminary conclusions were obtained:The subsoil moisture sensor provides the most important system information; it measures the moisture of the subsoil and indicates when it is necessary to activate the irrigation mechanism. In addition, it estimates the amount of water needed.The outdoor temperature sensor measures the outside temperature. If the temperature is high, this sensor prevents the watering process that, if activated, would simply result in water evaporation and unnecessary water wastage.The solar radiation sensor is as necessary as the outside temperature sensor, since sunlight causes water to evaporate.
