A method of monitoring an enclosed environment includes disposing a sensor assembly in an environment enclosed by an enclosure, where the sensor assembly includes a transmitter configured to communicate using near-field magnetic induction. A receiver is disposed outside the enclosure and configured to communicate with the transmitter using near-field magnetic induction. The receiver is to a communications device. The sensor assembly detects a sensed condition of the environment enclosed by the enclosure. The transmitter communicates the sensed condition to the receiver using near-field magnetic induction. After receiving the sensed condition from the receiver, the communications device communicates the sensed condition to a user.

1. A method of monitoring an enclosed environment within an enclosure, the method comprising: providing a system having a receiver and a transmitter, the receiver and the transmitter configured to wirelessly communicate using near-field magnetic induction;disposing a sensor assembly and the transmitter within the enclosure, and coupling the sensor assembly to the transmitter;disposing the receiver outside of the enclosure;coupling the receiver to a communications device outside the enclosure;detecting, by the sensor assembly, a sensed condition of the enclosed environment within the enclosure;communicating, by the transmitter, the sensed condition within the enclosure to the receiver outside of the enclosure using near-field magnetic induction;receiving, by the receiver, the sensed condition from the transmitter; andcommunicating, by the communications device, the sensed condition to a user outside of the enclosure. 2. The method of claim 1, wherein the communications device is selected from the group consisting of a computer, a cell phone, a radio, a display panel, a wireless-headset, and a cabled headset. 3. The method of claim 1, wherein the enclosure having walls surrounding the enclosed environment within the enclosure, and the enclosure is selected from the group consisting of a refrigerator, a freezer, an oven, a liquid-storage tank, a liquid-transport trailer, a pipe, a cargo trailer, and a cargo container. 4. The method of claim 1, wherein the enclosure is made of a shielding material that attenuates transmission of electromagnetic waves. 5. The method of claim 4, wherein the shielding material comprises a material selected from the group consisting of a metal sheet, a metal wire mesh, metal-reinforced concrete, and metal structural members. 6. The method of claim 1, wherein the environment is gaseous. 7. The method of claim 1, wherein the environment is a liquid. 8. The method of claim 1, further comprising: the transmitter and the receiver both operating with low-frequency non-propagating magnetic fields of less than 900 MHz. 9. The method of claim 1, wherein the step of providing includes selecting one of the transmitter and the receiver configured to be capable of transmitting and receiving simultaneously. 10. The method of claim 1, further comprising: detecting a first sensed condition of the environment, wherein the first sensed condition of the environment is one of temperature, humidity, movement, pressure, and flowrate; anddetecting a second sensed condition of the environment within the enclosure, wherein the second sensed condition of the environment is a further one of temperature, humidity, movement, pressure, and flowrate. 11. The method of claim 1, wherein the providing step includes: selecting the receiver having a first coil and a second coil;positioning the first coil to overlap the second coil thereby defining a second coil inner region and a second coil outer region, the second coil inner region having an inner region area, and the second coil outer region having an outer region area; andconfiguring the receiver as a transceiver antenna capable of transmitting and receiving simultaneously. 12.
