The SCD4x is Sensirions next-generation miniature CO2 sensor. This sensor builds on the photoacoustic sensing principle and Sensirions 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.

CO2 is a key indicator for indoor air quality as high levels compromise humans cognitive low power 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 concentrations for a healthy, productive environment.
