We develop innovative solutions and services for precision agriculture by applying the latest results of research and experimentation in the field of IoT technologies to the agricultural domain. Our solution leverages wireless battery-operated devices which collect field data with high granularity in combination with ultra-local models and machine learning to predict local crop conditions and assist farmers in taking the best decisions. We aim to help farmers shape the future of agriculture towards increased sustainability, by adopting solutions that increase crop yields and food quality while reducing agricultural inputs and preserving natural resources.
