At the International Sensor and Test and Measurement Technology Exhibition (Sensor+Test 2017), which took place from May 30 to June 1 in Nuremberg, environmental and flow sensors were a key focus. Solution expert Sheng Sirui introduced a new silicone-resistant metal oxide gas sensor — the Multi-pixel Gas Sensor SGP. This innovative device offers excellent long-term stability and is designed for advanced applications in smart homes, home appliances, and IoT systems.

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 opportunities for environmental monitoring. Thanks to its unique performance, 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 increased 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 commonly found in consumer products 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 is finally available.

This breakthrough marks a significant advancement in gas sensing technology, making it more suitable for real-world applications where reliability and consistency are essential. Whether in smart home systems, industrial monitoring, or portable devices, the SGP sensor sets a new standard in performance and durability. With its ability to withstand environmental contaminants, the SGP is paving the way for smarter, more accurate gas detection solutions across various industries.
