Abstract
A color change sensor assembly which changes color depending on temperature or time since activation is disclosed. The sensor assembly comprises an indicator that changes color based on the concentration of a gas. The assembly comprises a porous material containing the gas at concentrations higher than the gas is found in the atmosphere and the assembly is configured to control diffusion of the gas for example carbon dioxide into the color change indicator. The assembly is enclosed in an impermeable container that has high concentrations of the gas found in the porous material, allowing the sensor assembly to be activated by removing it from the packaging, providing a time-sensitive and temperature-sensitive indicator.
