Product Summary
The world's smallest digital gas sensor "SGP" opens up many new possibilities, including indoor air quality measurement.
The gas sensor features very high robustness against gas contamination in existing practical applications, with long-term stability and low drift performance. Small package size (2.45 x 2.45 x 0.9 mm3, DFN type) and a digital interface (I2In C), the digital gas sensor "SGP" equipped with a dustproof and waterproof membrane can be easily installed in various applications such as smart home products and home appliances.
Challenges of gas sensors
従来のガスセンサーはシロキサンの影響により、センシング部に金属酸化膜を張ってしまうという課題から長期安定や精度を著しく劣化させます。
Siloxanes are ubiquitous, originating from a variety of indoor environments (such as consumer products).
Sensirion solves siloxane problems
Sensirion gas sensors are the only sensors that are siloxane resistant.
長期安定性、精度にて他社と優位性があります。
