Abstract: A sensor node of a sensing network acquires first sensing data from an internal sensing node and/or second sensing data via an interface from an external sensing node. The sensor node is configured with a selected configuration file. The first and second events are detected as a function of the first and/or second sensing data based on the configuration file.
