The present application at least describes a non-transitory computer readable medium including program instructions that when executed by a processor effectuate a set of actions. The program instructions include causing a scan of a radio frequency spectrum to detect one or more radio signals transmitted within a pre-defined area. The program instructions also include causing a capture of a radio signal of interest from the one or more radio signals. The program instructions also include demodulating the radio signal of interest to determine coded sensor data carried thereon. The program instruction further include decoding the coded sensor data to determine a characteristic of the sensor data. The program instruction further include generating an alert based on the characteristic of the sensor data.
