This article compares CO2 sensor accuracy and response time in indoor air quality assessment, suggesting optimal options.
This article compares eight types of CO2 sensors using NDIR technology for accuracy, response time, and acquisition costs. The experiment included static and dynamic tests in a chamber and a duct. The Testo 935 and Rotronic CL11/CP11 sensors showed high accuracy and fast response, while the Winsen MH-Z16 offered the best performance-to-cost ratio. Other tested sensors – NetAtmo, Comet S3532, LaskaKit SCD41 and MH-Z14 exhibited inaccuracies, making them unsuitable for scientific applications.
