Mango Leaf Monitoring with Inductive and Capacitive Sensors and Its Comparison with Trunk Dendrometer Measurements

Mango is one of the main fruits grown in Mexico that are exported worldwide, but trees consume a lot water, and irrigation scheduling should be implemented to optimize water use. Dendrometers were installed fruit usage during 2019 2020. A capacitor with Teflon clamps pressurized leaf, its dielectric changed leaf content. Additionally, Hall sensors leaves study effect mango production. It was found capacitance tend more sensitive than magnetic field monitoring. Higher changes noted midday warm weather. Thresholds from can provide signals for scheduling.
