1. An environmental condition monitoring device comprising:
- an environmental reactive layer having a composition, the composition of the environmental reactive layer configured to alter in response to exposure to an environmental condition; and
an interferometric modulator, a reflectivity spectrum of the interferometric modulator being a function of the composition of the environmental reactive layer.

Abstract
An environmental condition sensing device includes an interferometric modulator with optical properties, which change in response to being exposed to a predetermined environmental threshold or condition. The device includes an environmental reactive layer, which alters composition, in an optically-detectable manner, in response to being exposed to a predetermined environmental threshold or condition.
