1. A passive radio frequency (RF) circuit comprises:
antenna circuitry including an antenna and a tuning circuit, wherein the antenna circuitry is operably coupled to:
receive an inbound RF signal via an inbound propagating electromagnetic wave; and
transmit an outbound RF signal via an outbound propagating electromagnetic wave;
a power harvesting circuit operably coupled to generate a supply voltage from the inbound RF signal;
a temperature sensor operable to, when the supply voltage is generated, generate a digital signal that represents a temperature;
a processing module operable to, when the supply voltage is generated, process the digital signal to produce a digital representation of the temperature; and
an RF transmitter operable to, when the supply voltage is generated, transmit, via the antenna circuitry, the outbound RF signal that includes the digital representation of the temperature.
