- a magnetic resonator disposed within a confined environment;
an interrogating antenna inductively coupled to the magnetic resonator, the interrogating antenna situated outside the confined environment and configured to emit one or more energizing signals to wirelessly energize the magnetic resonator, wherein a condition associated with the confined environment is determined based at least in part on a resonant signal response of the magnetic resonator received by the interrogating antenna from the magnetic resonator in response to the magnetic resonator being energized; and
a computing device coupled to the interrogating antenna, wherein the computing device comprises;
a processor in data communication with a memory;
a radio frequency (RF) generator that is configured to generate the one or more energizing signals emitted from the interrogating antenna; and
a condition monitoring application executable in the computing device, the condition monitoring application being configured to at least;
determine, via the computing device, whether a resonant frequency of the resonant signal response resonating from the magnetic resonator is higher than a prior resonant frequency of the magnetic resonator; and
in response to determining that the resonant frequency of the magnetic resonator is higher than the prior resonant frequency, determine, via the computing device, a condition value of the condition based at least in part on a comparison with the resonant frequency and a predefined correlation table.

Abstract
Disclosed are various embodiments of systems and methods related to measuring one or more ambient conditions within a confined environment. A telemetry monitoring system comprises a magnetic resonator disposed within a confined environment. The magnetic resonator may be passively energized by an interrogating antenna situated outside the confined environment. Resonant signal responses emitted from the magnetic resonator may be analyzed to determine one or more ambient conditions within the confined environment.
