New CO2 sensors for air quality monitoring

Air Quality Sensor
A CO2 sensor has been developed for specialist applications in air quality monitoring and control, offering good long-term stability, high selectivity, and a low humidity dependence.The concentration of CO2 can be used as a good indicator of air quality in the office or in the home. Until now, an obstacle to the widespread adoption of control systems based on CO2 concentration measurement has been the lack of stable, accurate and yet economical sensors for this unreactive gas. Now, however, with the introduction of new solid electrolyte sensors, rapidly-reacting measurement systems for air quality control can be produced. The concentration of CO2 in fresh air is generally around 350 ppm (parts per million),
