    Multi-Pixel Gas Sensors

    The multi-pixel gas sensor platform SGP creates new possibilities for the measurement of indoor air quality. The SGP offers a complete gas sensor system integrated into a very small DFN package featuring an I2C interface and fully calibrated air quality output signals.

    Sensirion’s MOXSens® Technology provides the SGP with an unmatched robustness against contamination by siloxanes resulting in unique long-term stability and accuracy. The SGP further combines multiple metal-oxide sensing elements − the pixels – on one chip to provide more detailed air quality signals. The unprecedented combination of long-term stability and multi-pixel technology makes the SGP a perfect choice for indoor air quality monitoring in mobile, smart home and appliance applications.


    Long-term stability of metal-oxide gas sensors

    Traditional metal-oxide gas sensors suffer from poor long-term stability caused through irreversible contamination by siloxanes.

    Siloxanes are everywhere

    • Indoor environments
    • «Most abundant VOC emitted by humans»
    • Consumer products

     

    Siloxanes destroy metal-oxide sensors

    • Significant loss of VOC sensitivity
    • Strong increase of response time

     

    Solution

    Sensirion’s proprietary MOXSens® Technology provides the SGP with an
    unmatched robustness against siloxanes, resulting in unique long-term
    stabilityand accuracy.


    Unique performance thanks to MOXSens® Technology

    The sensing principle of the SGP is based on a heated film of metal-oxide (MOx) nanoparticles. Adsorbed oxygen on the metal-oxide particles reacts with the target gas and thereby releases electrons. This results in a change of the electrical resistance of the metal-oxide layer that is measured by the sensor.

    The SGP multi-pixel gas sensor platform integrates four sensing elements − the pixels – into one small DFN package. Using Sensirion’s CMOSens® Technology, the SGP offers a complete sensor system on a single chip featuring a digital I2C interface, a temperature-controlled microhotplate, as well as preprocessed and calibrated indoor air quality signals.

    Optimized metal-oxide sensing materials in combination with Sensirion’s multi-pixel gas measurement platform result in a unique resistance against contamination by siloxanes – MOXSens® Technology. Sensirion’s MOXSens® Technology enables highly sensitive and reliable gas measurements of indoor air pollutants such as volatile organic compounds and hydrogen.


    Environmental Sensing

    Sensirion Environmental Sensing Infographic

    Environmental conditions have a major impact on our well-being, comfort, and productivity. Sensirion’s sensor solutions provide detailed and reliable data on key environmental parameters such as humidity, temperature, volatile organic compounds (VOCs), particulate matter (PM2.5), and CO2. Environmental Sensing opens up new possibilities to create smarter devices that improve our comfort and well-being as well as increase energy efficiency in a wide variety of applications.

    We accompany you through the entire product development process, from the initial idea to product launch and beyond. Our expertise ranges from prototype construction, design-in support and use-case development to inline testing at the mass production stage.
