SCD40 Photoacoustic CO2 Air Quality Sensor Carbon Dioxide SMD Assembly

Place of Origin: Switzerland
Brand Name: Sensirion
Model Number: SCD40

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.
