Sensirion SCD40-D-R1
The SCD4x is Sensirion’s next generation miniature CO2 sensor. This sensor builds on the photoacoustic NDIR sensing principle and Sensirion’s patented PASens® and CMOSens® technology to offer high accuracy at an unmatched price and smallest form factor.FEATURES
● Photoacoustic NDIR sensor technology PASens®● Smallest form factor: 10.1 x 10.1 x 6.5 mm3
● Reflow solderable for cost-effective assembly
● Digital I2C interface
● Integrated temperature and humidity sensor Product Variants
● SCD40: Base accuracy, specified measurement range 400 –2’000 ppm
● SCD41: High accuracy, specified measurement range 400 – 5’000 ppm, compatible with relevant IAQ standards, several power modes Product Summary 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 (IAQ) as high levels compromise humans’ cognitive performance 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 concentration for a healthy, productive environment.
