Application of CO2 NDIR gas sensors in air quality monitoring

This paper explains the use of Non-Dispersive InfraRed (NDIR) sensor that is built into the complex system for the air quality monitoring. It is known that CO2 is an important
indicator of the current state of the environment, especially in urban areas and indoor air quality.

Latest CO2 NDIR gas sensors are low cost, low power consumption, miniature and have a long lifetime so that the increasingly built into new systems for measuring environmental parameters. By using commercially available detectors and advanced knowledge of the design of electronic circuits, measuring the concentration of CO2 is explained in detail in this paper.

In this paper NDIR sensors are discussed, targeting only commercially available solutions for measuring CO2 concentration. As a representative of NDIR sensors, Alphasense IRC-A1 sensor is selected. This sensor will be used as an example to explain the principles of operation of NDIR sensors. It will also be explained electronic circuit for processing signals from the sensor and the methods to calculate the final concentration of CO2 from collected data. Finally, an example of measurement in field conditions with a detailed analysis is given.
