Get A QuoteThe Sensirion SGP41 combines VOC and NOx sensing in an ultra-compact 2.44 × 2.44 × 0.85 mm package. It provides a 0–500 VOC Index and NOx sensing capability, with a VOC measurement range of 0–1000 ppm and response time below 10 seconds. Its robust multi-pixel sensing element offers strong resistance to contaminating gases and long-term stability. With I²C communication, 1.7–3.6 V supply, and standard SMD assembly compatibility, the SGP41 is well suited for high-volume indoor air-quality applications.
