At this year's International Sensor and Test and Measurement Technology Exhibition (Sensor+Test 2017, May 30–June 1, Nuremberg), environmental and flow sensors were on display. Solution expert Sheng Sirui introduced a silicone-resistant metal oxide gas sensor — the Multi-pixel Gas Sensor SGP. This new sensor offers excellent long-term stability and is designed for smart home, home appliance, and IoT applications.

Anti-silicone gives metal oxide gas sensors permanent stability

The SGP gas sensor is based on Sirius’ multi-pixel platform, integrating four gas sensing components into a compact 2.45x2.45x0.9mm DFN package. It delivers a fully calibrated air quality output signal. The combination of long-term stability and multi-pixel technology opens up new possibilities for environmental monitoring. Thanks to its unique performance, the SGP makes it possible to integrate metal oxide gas sensors into mobile devices for the first time.

Traditional metal oxide gas sensors often suffer from a rapid decline in sensitivity and an increase in response time over time due to difficulty in achieving long-term stability. This degradation is typically caused by irreversible contamination from compounds like siloxanes, which are common in consumer and industrial environments. Sheng Sirui’s proprietary metal oxide technology and multi-pixel platform make the SGP highly resistant to such contaminants, ensuring unmatched long-term stability and accuracy. Now, a reliable metal oxide gas sensor equipped with SGP technology has finally become a reality.

This innovation marks a significant step forward in gas sensing technology, offering users a more accurate and durable solution for real-time environmental monitoring. Whether for smart homes, industrial applications, or wearable devices, the SGP sensor is setting a new standard in the field of gas detection.
