1. A system comprising:
a sensor sized to be within a reservoir of a machine having moving parts that are lubricated by a liquid in the reservoir, the sensor configured to obtain a measurement of the liquid that is representative of one or more of a quantity or a quality of the liquid in the reservoir; and
a device body operably coupled with the sensor, the device body including a processing unit and a transponder, the transponder configured to wirelessly receive an interrogation signal from a remote reader that also energizes the processing unit to generate a data signal representative of the measurement of the liquid obtained by the sensor, the interrogation signal additionally energizing the transponder to wirelessly communicate the data signal to the remote reader;
wherein the measurement is at least one of a temperature of the liquid or nearby components, a fluid conduction of the liquid, a dielectric constant of the liquid, an impedance of the liquid, or a viscosity of the liquid, and the data signal wirelessly communicated to the remote reader relates to the measurement.
