The SGP30 is a digital multipixel gas sensor designed for easy integration. The SGP30 is a complete sensor on a single chip an integrated i2c data interface with a temperature controlled micro hotplate and two preprocessed indoor air quality signal that includes a metal-oxide gas sensor in a multiple sensing element on a SMD package, the SGP30 delivers more detailed data about air quality typical and maximum accuracy tolerance in percent of measured value at 25 degree Celsius.

The contamination gases preset in real world application enabling a unique long-term stability and low drift.  The SGP30 can be integrated into air purifier, controlled ventilation, handheld devices for special purpose, and IOT applications. For more technical details please refer to the datasheet below.
