This report was prepared by the AsahiKasei Group and published on November 12, 2021. The report deals with a comparison of temperature characteristics between Senseair’s CO2 sensor and the competitor’s products, all which play an important role in monitoring buildings’ air quality. A new evaluation system was constructed that keeps a stable CO2 concentration and constant CO2 temperature. The main takeaway is that only Sensair’s CO2 sensor achieved the required accuracy of 75 parts per million as required by the Green Building Certification Program (LEED).
