SCD40 Photoacoustic CO2 Air Quality Sensor Carbon Dioxide SMD Assembly

Product Description
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.
