Sensirion SGP41 CMOSens®/MOXSens® Digital Air Quality Sensor

Sensirion SGP41 CMOSens®/MOXSens® Digital Air Quality Sensor is 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. The sensing element and Gas Index Algorithm feature high robustness against contaminating gases present in air-quality applications enabling unique long-term stability and low drift. Measuring 2.44mm² x 0.85mm, the DFN packaged gas sensor enables applications in limited spaces. The Sensirion SGP41 CMOSens®/MOXSens® Digital Air Quality Sensor is designed for easy integration into air purifiers or demand-controlled ventilation systems.
