Petiole is a mobile-based recommendation system for precision agriculture. It monitors dynamics of plant growth using leaf-area measurement, helping to understand how a plant reacts to different factors (weather, growth promoters, etc.). It is like a smart tracker for plant growth.
Petiole has a mobile app to make leaf-area measurement and data cloud service to collect, process data and show dynamics of growth in an affordable manner. After tweaking this service, the next steps for Petiole are to quantify leaf greenness and make diagnostics of leaf disease.
