SENSIRION Gas Detection Sensor, Carbon Dioxide, 40000 ppm, PAsens CMOSens SCD4x Series

The SCD4x is Sensirion’s next-generation miniature CO2 sensor. This sensor builds on the photoacoustic 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.

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.
