A method of performing contact tracing of persons on a network is provided. The method includes obtaining temperature data comprising one or more temperature readings for a first person associated with a first sensor assembly of a plurality of sensor assemblies on the network. The method includes determining whether the one or more temperature readings for the first person exceeds a threshold temperature. Responsive to determining the one or more temperature readings exceeds the threshold temperature, the method includes determining, by the one or processors, whether a second sensor assembly of the plurality of sensor assemblies is within a predetermined proximity of the first sensor assembly. Responsive to determining the second sensor assembly is within the predetermined proximity of the first sensor assembly, the method includes providing a notification indicative of a second person associated with the second sensor assembly being within the predetermined proximity of the first person.
