CO₂ sensor with best-in-class accuracy, excellent long-term stability and robustness
The SCD53 combines Sensirion’s leading expertise in photoacoustic NDIR sensing with advanced laser technology for excellent long-term stability independent of fresh-air based recalibration algorithms. Furthermore, the sensor provides best-in-class accuracy with robustness against dust, vibrations or mechanical forces. Integrated humidity and temperature compensation, as well as optional pressure correction, enable reliable readings across a demanding range of environmental conditions. On-demand measurements, compact sensor size and a reflow solderable LGA package make integrating SCD53 simple, flexible and cost-efficient.
