Sensirion SGP
Multi-Pixel Gas Sensors for Measuring Indoor Air Quality
Unique Performance Thanks to MOXSens® Technology
The SGP gas sensors offer a complete sensor system integrated into a very small 2.45 × 2.45 × 0.9 mm3 DFN package featuring an I2C interface
and fully calibrated air quality output signals. Sensirion’s MOXSens® Technology enables highly sensitive and reliable measurements of typical
indoor pollutants like volatile organic compounds or hydrogen. The SGP further combines multiple metal-oxide sensing elements on one chip to
provide more detailed air quality signals.
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
stability and accuracy.
MEASUREMENT PRINCIPLE
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 micro-
hotplate, 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.

FAST AND EASY EVALUATION FOR YOUR SENSOR APPLICATION
The evaluation kit SEK-Environmental Sensing is designed for an
quick, easy and cost-efficient evaluation of Sensirion's environmental
sensors. This faciliates to evaluate sensors and develop innovative
sensor applications.
The kit combines plug-and-play hardware with an easy-to-use viewer
software for in-depth evaluation, the ControlCenter. Each evaluation
kit includes a Sensirion SensorBridge, all required connector cables,
as well as various sensor samples. The SensorBridge features two
independent I2C channels that allow simultaneous evaluation of two
environmental sensor samples. The ControlCenter viewer software
makes it possible to display and log the sensor signals for multiple
sensors connected to several SensorBridges on the same PC.
