Abstract
An RF addressable sensor network includes one or more RF addressable sensors; one or more wireless sensor readers coupled to a communications network; and one or more end user devices coupled to the communications network. The one or more wireless sensor readers communicate with the one or more RF addressable sensors to obtain sensor data for transmission over the communications network. A wireless sensor reader includes at least one antenna configured for communication with the one or more RF addressable sensors, a controller, a network communications module coupled to the controller, the network communications module having an interface for coupling to a communications network, a logic module coupled to the controller, and a user interface. The logic module includes a sensor communications module for receiving sensor data from the one or more RF addressable sensors.
