Low cost, mobile sensor system for measurement of carbon dioxide in permafrost areas

In this work a novel concept based on low power semiconducting, mid infrared components and new, low cost measurement cells for use in harsh environmental conditions, such as permafrost areas, is presented. Due to the small changes of the environmen tal carbon dioxide (CO2) concentration in this area a high resolution of 5 ppm CO2 is required. The current sensor design achieves a resolution of up to 6 ppm CO2 and offers further optimization potential at overall low costs.
