SGP41

Product Introduction

The SGP41 is a digital gas sensor designed for easy integration into air purifiers or demand-controlled ventilation systems. Sensirion’s CMOSens® technology offers a complete, easy-to-use sensor system on a single chip featuring a digital I2C interface and temperature-controlled micro hotplates, providing one VOC and one NOx based indoor air quality signal. Both sensing element and Gas Index Algorithm feature an unmatched robustness against contaminating gases present in real-world applications enabling a unique long-term stability as well as low drift. The very small 2.44 x 2.44 x 0.85 mm3 DFN package enables applications in limited spaces. Sensirion’s state-of-the-art production process guarantees high reproducibility and reliability. Tape and reel packaging together with suitability for standard SMD assembly processes make the SGP41 predestined for high-volume applications.
