Microwave-based Nitrogen Dioxide Gas Sensor For Automotive Applications

As a consequence of global industrialization and the increased use of cars powered by gasoline, the level of environmental pollution (mostly by nitrogen dioxide) is increased year by year. There are a number of studies, where ambient nitrogen dioxide concentrations were measured, and currently, in many cities, smart air pollution sensors are installed. However, the problem of monitoring the nitrogen dioxide concentration on highways has not been solved. Herein, the preliminary results on the microwave-based NO

gas sensor for such the application are presented.
