Abstract
A device is disclosed herein. The device comprises a housing, a gas, an antenna, and a control module. The housing defines and hermetically seals an interior cavity. The gas is contained within the interior cavity of the housing at a pressure greater than atmospheric pressure. At least a portion of the antenna is within the interior cavity of the housing. The control module is operably coupled with the antenna to transmit an incident radio wave into the interior cavity of the housing and receive a reflected radio wave within the interior cavity of the housing. The control module is configured to determine a resonance frequency of the interior cavity of the housing based on, at least partially, the reflected radio wave, and determine the pressure of the gas contained within the interior cavity of the housing based on, at least partially, the resonance frequency of the interior cavity of the housing.
