Description: The SGP40 is a digital multi-pixel gas sensor designed for easy integration into air purifier, demand-controlled ventilation, and IoT applications. A complete sensor system on a single chip featuring a digital I2C interface, a temperature controlled micro hotplate, and two preprocessed indoor air quality signals. As the first metal-oxide gas sensor featuring multiple sensing elements on one chip, the SGP40 provides more detailed information about the air quality.The sensing element features an unmatched robustness against contaminating gases present in real-world applications enabling a unique long-term stability and low drift. The very small 2.45 x 2.45 x 0.9 mm 3 DFN package enables applications in limited spaces. High reproducibility and reliability. Tape and reel packaging, together with suitability for standard SMD assembly processes make the SGP40 predestined for high-volume applications.
