The SCD4x is Sensirion’s next generation miniature CO₂ sensor that offers an unmatched price-to-performance ratio. Tape and reel packaging combined with its SMD assembly processing make the SCD4x ideal for high-volume applications. This sensor builds on the photoacoustic sensing principle and Sensirion’s patented PASens® and CMOSens® Technology to enable unmatched small sensor size combined with high performance. SMD compatibility and the small footprint allow cost- and space-effective integration to boost freedom of design for customers. The integrated best-in class humidity and temperature sensor enables superior on-chip signal compensation and addition RH and T outputs. Finally, the large supply voltage (2.4 V – 5.5 V), the robustness towards external stresses and the adjustable power consumption make the SCD4x the perfect fit for varying customer needs.
