SCD40 Air Quality CO2 Sensor Carbon Dioxide Photoacoustic
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 build-in SHT4x humidity and temperature sensor.
