SCD41-D-R1

The SCD4x is Sensirion’s next generation miniature CO2 sensor. This sensor builds on the photoacoustic NDIR sensing principle and Sensirion’s patented PASens® and CMOSens® technology to offer high accuracy at an unmatched price and smallest 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. Tape and reel packaging make the SCD4x ideal for high-volume applications.

The SCD41 delivers several important features for applications in low power and indoor air quality, such as a specified CO2 accuracy range of up to 5’000 ppm, higher accuracy specifications and low power measurement modes.

CO2 is a key indicator for indoor air quality (IAQ) as high levels compromise humans’ cognitive performance and well-being. The SCD4x enables smart ventilation systems to regulate ventilation in the most energy-efficient and human-friendly way. Moreover, indoor air quality monitors and other connected devices based on the SCD4x can help maintain low CO2 concentration for a healthy,  productive environment.
