Claim:
An assembly, comprising: a sealed housing; at least one moisture-sensitive component disposed of within the sealed housing; a first sensor element operable to generate a first signal in response to moisture in a first state being present at a first predetermined level within the sealed housing; a first valve element coupled to the housing and, in response to the first signal, operable to enable at least a portion of the moisture to exit the housing at the first valve element; a second sensor element operable to generate a second signal in response to moisture in a second state being present at a second predetermined level within the sealed housing; a third sensor element operable to sense that a pressure outside the housing is less than a pressure within the housing; and a second valve element coupled to the housing and, in response to the second signal, operable to enable at least a portion of the moisture to exit the sealed housing at the second valve element if and only if the pressure level inside the sealed housing is greater than a pressure level outside the sealed housing.
