FEATURES
● Photoacoustic NDIR sensor technology PASens®● Smallest form factor: 10.1 x 10.1 x 6.5 mm3
● Reflow solderable for cost effective assembly
● Large output range: 0 ppm – 40’000 ppm
● Large supply voltage range: 2.4 – 5.5 V
● High accuracy: ±(40 ppm + 5 %)
● Digital I2C interface
● Integrated temperature and humidity sensor
● Low power operation down to < 0.4 mA avg. @ 5 V, 1 meas. / 5 minutes 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 build-in SHT4x humidity and temperature sensor. CO2 is a key indicator for indoor air quality as high levels compromise humans’ cognitive performance and wellbeing. 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 maintaining low CO2 concentration for a healthy, productive environment.
