SCD40-D-R2 in Sensirion SCD4x Family
The SCD40-D-R2 is a high-performance carbon dioxide sensor from Sensirion, part of the revolutionary SCD4x miniaturized series. Utilizing photoacoustic sensing principles, it integrates CO2, temperature, and humidity measurement into a single 10.1 x 10.1 x 6.5 mm SMD package. This family is designed for high-volume integration where PCB real estate is limited, providing high-accuracy environmental monitoring for smart HVAC systems, indoor air quality monitors, and industrial automation equipment requiring low power consumption and long-term stability.
Variants in This Sub-Family
The SCD40-D-R2 represents the base variant within the SCD4x sub-family, optimized for standard indoor air quality ranges up to 2,000 ppm. While the physical package remains identical across the series, other variants like the SCD41 offer an extended measurement range up to 5,000 ppm and specialized single-shot operating modes for further power optimization. Selection depends on the specific ppm ceiling and power budget required by the target application.
