      • Formaldehyde Sensor SFA30

        Formaldehyde Sensing Made Easy

        The SFA30 is Sensirion’s new digital formaldehyde sensor designed for easy integration into air purifiers, demand-controlled ventilation systems, or indoor air quality monitors. Based on Sensirion’s electrochemical technology, the SFA30 offers excellent formaldehyde sensing performance with a uniquely low cross-sensitivity to other VOCs. The sensor module’s on-board SHT sensor provides accurate humidity and temperature readings and enables a fully temperature/humidity compensated and factory calibrated formaldehyde concentration output in ppb.

    VOC Sensor SGP30 / SGPC3 (NRND)

    Warning Image

    Not Recommended for New Designs (NRND)

    The SGP30 and SGPC3 are not recommended for new designs anymore.

    SGP30 and SGPC3 will be replaced by SGP40 (see transition guide). For more information, please contact supportsensirioncom.

    For HVAC and Indoor Air Quality Applications

    The SGPxx is a digital multi-pixel gas sensor platform designed for easy integration into air purifier, demand-controlled ventilation, and IoT applications.

    The SGP30 has been designed for smart home, appliance and Internet of Things applications. It features two calibrated air quality signals and on-chip humidity compensation. In addition, with the SGPC3, Sensirion offers a low power solution that makes reliable gas sensing available for mobile applications.


    Sensirion’s CMOSens® Technology offers a complete sensor system on a single chip featuring a digital I2C interface, a temperature controlled micro hotplate, and two preprocessed indoor air quality signals. As the first metal-oxide gas sensor featuring multiple sensing elements on one chip, the SGP3x provides more detailed information about the air quality. The sensing element features an unmatched robustness against contaminating gases present in real-world applications enabling a unique long-term stability and low drift. The very small 2.45 x 2.45 x 0.9 mm3 DFN package enables applications in limited spaces. Sensirion’s state-of-the-art production process guarantees high reproducibility and reliability. Tape and reel packaging, together with suitability for standard SMD assembly processes make the SGP30 predestined for high-volume applications.
