SparkFun SEN-16531 Air Quality Sensor SGP30 (Qwiic)

Through tracking the volatile organic compounds around the sensor, the SparkFun SGP30 Air Quality Sensor (SEN-16531) provides information on the air quality in your room or Home. Within 15 seconds of power up, the SGP30 Air Quality Sensor can return valid indoor air quality ( IAQ) readings! By contrast, traditional air quality (IAQ) sensors are nice to calculate CO2 and volatile organic compounds ( VOCs), but some require a 48-hour burn-in time and a 20-minute start time.

Along with very fast startup time, the SGP30 is highly resistant to contamination from other gases to ensure extremely reliable results in low drift and long-term stability. You can read the SGP30 gas sensor output measurements of total VOCs (TVOC) in parts per billion (ppb), carbon dioxide (CO2) equivalent in parts per million (ppm) and H2.

The SGP30 communicates via I2C so naturally we broke out the pins on the sensor to Qwiic connectors so you can easily connect it to SparkFun’s ever growing Qwiic Ecosystem!
