This is a Adafruit SGP30 Air Quality Sensor Breakout VOC and eCO2 STEMMA QT / QwiicRoHS Compliant.

Breathe easy with the SGP30 Multi-Pixel Gas Sensor, a fully integrated MOX gas sensor. This is a very fine air quality sensor from the sensor experts at Sensirion, with I2C interfacing and fully calibrated output signals with a typical accuracy of 15% within measured values. The SGP combines multiple metal-oxide sensing elements on one chip to provide more detailed air quality signals.

This is a Adafruit SGP30 Air Quality Sensor Breakout VOC and eCO2 STEMMA QT / QwiicRoHS Compliant that can detect a wide range of Volatile Organic Compounds (VOCs) and H2 and is intended for indoor air quality monitoring. When connected to your microcontroller (running our library code) it will return a Total Volatile Organic Compound (TVOC) reading and an equivalent carbon dioxide reading (eCO2) over I2C.

The SGP30 has a standard hot-plate MOX sensor, as well as a small microcontroller that controls power to the plate, reads the analog voltage, tracks the baseline calibration, calculates TVOC and eCO2 values, and provides an I2C interface to read from. Unlike the CCS811, this sensor does not require I2C clock stretching.

This part will measureeCO2(equivalent calculated carbon-dioxide) concentration within a range of 400 to 60,000 parts per million (ppm), andTVOC(Total Volatile Organic Compound) concentration withina range of0 to 60,000 parts per billion(ppb).

Please note, this Adafruit SGP30 Air Quality Sensor Breakout VOC and eCO2 STEMMA QT / QwiicRoHS Compliant, like all VOC/gas sensors, has variability and to get precise measurements you will want to calibrate it against known sources! That said, for general environmental sensors, it will give you a good idea of trends and comparison. The SGP30 does have built in calibration capabilities, note that eCO2 is calculated based on H2 concentration, it is not a true CO2 sensor for laboratory use.
