SCD43
UpcomingHigh CO₂ accuracy with comprehensive building standard compatibility
The SCD4x is Sensirion’s second generation of optical CO₂ sensors. The sensor series builds on the photoacoustic NDIR sensing principle and Sensirion’s patented PASens® and CMOSens® technology to offer high accuracy at an attractive price and small form factor. SMD assembly allows cost- and space-effective integration of the sensor combined with maximal freedom of design. On-chip signal compensation is realized with the built-in SHT4x humidity and temperature sensor.
SCD43 delivers a best-in-class accuracy specification of +- (30pm + 3% m.v.) as well as compatibility with the most stringest building stardards, including ANSI/ASHRAE 62.1-2022 Draft Addendum d, California Title 24, RESET® grade B and WELL Building Standard™ (WELL v2). Furthermore, SCD43 features an extended specified range up to 5'000 ppm and single shot operation mode.
