SGP40 Datasheet PDF - Sensirion AG Switzerland

Product Summary
The SGP40 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 a temperaturecontrolled micro hotplate, providing a humiditycompensated VOC based indoor air quality signal. The output signal can be directly processed by Sensirion’s powerful VOC Algorithm to translate the raw signal into a VOC Index as a robust measure for indoor air quality. The VOC Algorithm automatically adapts to the environment the sensor is exposed to. Both sensing element and VOC Algorithm feature an unmatched robustness against contaminating gases present in real-world applications enabling a unique long-term stability as well as low drift and device-to-device variation. 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 SGP40 predestined for highvolume applications.
