Optimized CO2 Gas Sensor for Autonomous Measurement of Ocean Carbon

The objective of the proposed work is to create low cost, low power sensors for autonomous measurement of ocean carbon. In our Phase I effort, we showed that Dioxide Materials’ miniature CO2 sensors have the speed and sensitivity to meet NOAA’s requirements for sensing ocean carbon. The objective of the proposed work is to further develop the sensors so that they can be used directly in NOAA’s existing ocean carbon measurement system. Work incudes temperature compensation, so the devices can work in the Arctic, interface changes so the devices can communicate with NOAA’s existing hardware, and other changes. At the end of the program we propose doing a field test at NOAA’s location so we can verify performance for the intended application.
