Systems and methods for post-harvest crop quality management

A method for managing post-harvest fumigation processes in a crop storage area, comprising:

• between a group of edge devices deployed within a crop storage area, establishing a wireless ad hoc network and transmitting from a gateway device of the wireless ad hoc network measurement data concerning measurements made by sensors of the edge devices of physical environment parameters local to each respective sensor, wherein said gateway device collects the measurement data from the edge devices and transmits said measurement data using a fog agent executing on the gateway device and said measurement data includes some or all of measurements of temperature, gas/fumigant concentrations, and moisture content and/or relative humidity;
• at a server, receiving the measurement data transmitted by the fog agent of the gateway device, processing the received measurement data using a processor running a computational model defined by a system of differential equations to relate a plurality of physical descriptors of contents of the crop storage area and an environment of the crop storage area, and determining by the server, using the computational model, an approximate fumigant concentration profile for the crop storage area;
• predicting, by the server, an amount of living invertebrate pests and their pre-adult stages for a range of time points based on the fumigant concentration profile;
• and
• presenting, via a user interface at a client device communicatively coupled to the server, a periodically updated estimate for a time remaining for a fumigation process to eradicate living invertebrate pests and their pre-adult stages to an amount according to predictions made by the server,
• wherein the user interface is configured to visually represent progress of the fumigation process.
