Adafruit SGP30 Air Quality Sensor Module VOC/eCO2 - STEMMA QT/Qwiic I2C
The Adafruit SGP30 is a fully integrated MOX gas sensor module providing calibrated TVOC and eCO2 readings via I2C interface. It features onboard voltage regulation and level shifting for seamless 3.3V/5V compatibility with Arduino, Raspberry Pi, and other microcontrollers.
Features
- Measures TVOC (0-60,000 ppb) and equivalent CO2 (400-60,000 ppm)
- I2C interface with STEMMA QT / Qwiic connectors for solderless wiring
- Onboard 1.8V regulator and 3.3V/5V logic level shifting
- Built-in baseline calibration and humidity compensation input
- Compact PCB breakout with standard header pin access

The SGP30 Multi-Pixel Gas Sensor from Sensirion integrates multiple metal-oxide sensing elements on a single chip to deliver detailed air quality signals. It features an integrated microcontroller that manages the sensor heater plate, reads analog signals, performs baseline tracking, and calculates TVOC and eCO2 values, outputting them via a straightforward I2C protocol without requiring clock stretching.
Designed for indoor air quality monitoring, the sensor detects a broad spectrum of Volatile Organic Compounds (VOCs) and hydrogen. For optimal accuracy, the module supports external humidity compensation, where relative humidity data from a separate sensor can be written to the SGP30 over I2C to refine its calculations. The breakout board includes all necessary support circuitry, making it ready for integration into 3.3V or 5V logic systems.
