Description
The SCD41 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 build-in SHT41 humidity and temperature sensor.
