Carbon dioxide sensing device and method having an array of sensors on a single chip

Abstract

A carbon dioxide sensor package includes a housing having an opening. A filter membrane is mounted in the opening of the housing. A sensor is disposed within a cavity in the housing, the cavity being disposed beneath the opening, wherein the sensor is configured with first particles functionalizing an outer surface thereof to adsorb a target analyte in a presence of light, wherein the target analyte is carbon dioxide, and further configured to output data associated with a concentration of carbon dioxide sensed by the sensor. The package also includes an application specific integrated circuit disposed within the housing and configured to process data from the sensor and output processed data associated with the concentration of carbon dioxide. A light source is also disposed within the housing and configured to generate the light.
