Abstract

An environmental monitoring system including a base station. The base station may receive at least two reports from at least one environmental sensor in an environment; compute, based on values of physical properties of a simulated object and the at least two reports, a simulated condition of the simulated object within the environment; and transmit, to a computing device, the at least two reports and/or the computed simulated condition of the simulated object. A method of operating a base station of an environmental monitoring system. At least one computer-readable storage medium encoded with executable instructions that, when executed by at least one processor, cause the at least one processor to perform a method of operating a base station of an environmental monitoring system.
