Benefits & Characteristics

◾ Photoacoustic NDIR sensor technology PASens®

◾ Large output range: 0 ppm – 40’000 ppm

◾ Large supply voltage range : 2.4 – 5.5 V

◾ High accuracy: ±(40 ppm + 5 %)

◾ Modbus RTU (RS-485)

◾ Reflow solderable for cost effective assembly


    The HB0-CO2-01 is Sensirion’s next generation miniature CO2 . CO2 is a key indicator for
    indoor air quality as high levels sensor. This sensor builds on the photoacoustic NDIR
    compromise humans’ cognitive performance and well- sensing principle and Sensirion’s
    patented PAsens® and being. The HB0-CO2-01 enables smart ventilation systems to
    CMOSens® technology to offer high accuracy. SMD assembly human-friendly way.
    Moreover, indoor air quality monitors allows cost- and space-effective integration of the
    sensor and other connected devices based on the HB0-CO2-01 can combined with maximal
    freedom of design. On-chip signal help maintaining low CO2 concentration for a healthy,
    compensation is realized with the build-in HB0-CO2-01 humidity productive environment.
