8.1.2 Air Quality – Estimated Carbon Dioxide Correlation (eCO2)

A very reliable correlation can be made based on TVOC levels for situations where an elevated carbon dioxide (CO2) concentration is caused

by human occupancy, although the sensor module is not directly responsive to CO2. Renesas has developed a robust, patent pending,

correlation between elevated VOCs and CO2 attributable to human occupancy in a wide variety of living spaces, including homes and offices.

The measurement range for the eCO2 has its minimum at the atmospheric background level at 400ppm and ranges up to 5000ppm. The

correlation can predict the CO2 level as shown in Figure 4. Additional details about Renesas’ CO2 correlation are available in the ZMOD4410

Application Note – Estimating Carbon Dioxide.
