Sensirion’s CMOSens technology offers 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 SGP30 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 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 SGP30 predestined for high-volume applications.\n\nLibDriver SGP30 is a full-featured driver for SGP30, launched by LibDriver.It provides TVOC reading, CO2 eq reading, temperature reading, humidity correction and additional features. LibDriver is MISRA compliant.\n\n### Table of Contents\n\n  - [Instruction](#Instruction)\n  - [Install](#Install)\n  - [Usage](#Usage)\n    - [example basic](#example-basic)\n    - [example advance](#example-advance)\n  - [Document](#Document)\n  - [Contributing](#Contributing)\n  - [License](#License)\n  - [Contact Us](#Contact-Us)\n\n### Instruction\n\n/src includes LibDriver SGP30 source files.\n\n/interface includes LibDriver SGP30 IIC platform independent template.\n\n/test includes LibDriver SGP30 driver test code and this code can test the chip necessary function simply.\n\n/example includes LibDriver SGP30 sample code.\n\n/doc includes LibDriver SGP30 offline document.\n\n/datasheet includes SGP30 datasheet.\n\n/project includes the common Linux and MCU development board sample code.
