ardeusi.gr it's an integrated tool in hands of the farmer for the facilitation and more precise implementation of irrigation. The ideal amount of irrigation water is calculated from the web application based on the needs of the crops. At the same time, a set of sensors available in the system determines parameters of irrigation in real time, giving solution to the problems of irrigation. In addition, it is possible to fully automate irrigation with remote control of pumps or valves, both with time scheduling and with the needs of the crop by using the current measurement of soil moisture or other quality characteristics of the crop. Inefficient irrigation of agricultural holdings is a combined result of over-irrigation of crops, the increasing occurrence of pests, diseases and weeds, the reduction of production quantity, the degradation of production quality and the removal of nutrients from the soil. The novelty of ardeusi.gr is based on the use of technologies based on IoT (Internet of Things) and sensors, giving the ability to calculate the ideal amount of irrigation water for multiple crops separately and for different plots. Precise identification of needs ensures the reduction of production costs while improving the quantity and quality of production. Advantages: Irrigation optimization Reduction of poduction cost Cost savings Increase production
