## Abstract

An electronic device including a housing having an interior gas space, at least one electronic component positioned within the housing, an environmental control module positioned within the housing, wherein the environmental control module contains a sorbent, and a relative humidity sensor in communication with the interior gas space, wherein the interior gas space is maintainable at a relative humidity of 0% as measured by the relative humidity sensor. The interior gas space may include between about 97% and about 99.9% helium expressed as a molar fraction and at least a portion of the remainder as molecular oxygen. The sorbent can include at least one of a type A zeolite, a type X zeolite, or a type Y zeolite.

## Claims

### Claim 1

An electronic device comprising:
a housing having an interior gas space;
at least one electronic component positioned within the housing;
an environmental control module positioned within the housing, wherein the environmental control module contains a sorbent configured to provide and maintain a desired relative humidity within the interior gas space; and
a relative humidity sensor in communication with the interior gas space,
wherein the interior gas space is maintained at a relative humidity of 0% at all operating temperatures of the electronic device, as measured by the relative humidity sensor; and
wherein the interior gas space comprises a composition comprising helium of 99.9% or less expressed as a molar fraction and molecular oxygen in an amount between 0.1% and 3%.

### Claim 2 (depends on 1)

The electronic device of claim 1, wherein the sorbent comprises at least one of a type A zeolite, a type X zeolite, and a type Y zeolite.

### Claim 3 (depends on 1)
