SparkFun Air Quality Sensor - SGP30 (Qwiic)

The SparkFun SGP30 Air Quality Sensor provides information on the quality of the air in your room or house by monitoring the volatile organic compounds around the sensor. The SGP30 Air Quality Sensor can return valid indoor air quality (IAQ) readings within 15 seconds of powering up! By comparison, typical air quality (IAQ) sensors are great for measuring CO2 and volatile organic compounds (VOCs) but some of them require a burn-in time of 48 hours and a 20-min start up time.

Along with a very quick start-up time, the SGP30 from Sensirion is very resistant to contamination from other gases to ensure low drift and long-term stability for extremely reliable results. 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!

The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

The SGP30 Air Quality Sensor can also be automatically detected, scanned, configured, and logged using the OpenLog Artemis datalogger system. No programming, soldering, or setup required!

Need a custom board? This component can be found in SparkFun's À La Carte board builder. You can have a custom design fabricated with this component - and your choice of hundreds of other sensors, actuators and wireless devices - delivered to you in just a few weeks.

SparkFun Air Quality Sensor - SGP30 (Qwiic) Hookup Guide

June 5, 2020

A hookup guide to get started with the SparkFun Air Quality Sensor - SGP30 (Qwiic).

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

CO2 Sensor Seminar

I held a seminar for faculty and staff at the college where I am an adjunct. Participants built their own CO2 sensor in a 2 hour on-line class. The sensors worked perfectly and I have to say, people were impressed. Most had never done anything like this before either so, I think I inspired some new Makers. Thanks once again to Sparkfun for all you do!
