Easy to integrate with Arduino
Found plenty of libraries online to get this running quickly. The wiring is straightforward. Only giving 4 stars because the baseline calibration takes a while to stabilize.

Perfect for DIY Air Quality Monitors
This SGP30 module works flawlessly with my ESP32 project. The I2C communication is stable, and the eCO2 readings seem accurate when compared to a professional meter. Great value for the price.

Good sensor, requires calibration time
The sensor provides consistent data after the initial 7-day calibration period mentioned in the datasheet. Make sure to let it run continuously for best results. Documentation could be slightly better.

Reliable and compact
Small form factor makes it easy to fit into custom enclosures. The data output is clean and ready for logging. Highly recommend for anyone building air quality dashboards.

Excellent for monitoring plant environments
I use this to monitor CO2 levels in my indoor garden. It helps me know when to ventilate the room. The TVOC reading also alerts me if there are any unusual chemical smells.

Works well but sensitive to humidity
The sensor works as expected, but I noticed readings drift slightly in very high humidity conditions. Adding a separate humidity sensor for compensation solved the issue.
Q: Is the I2C address configurable?
A: No, the SGP30 has a fixed I2C address of 0x58. If you need multiple sensors, you will need an I2C multiplexer.
Q: Does this module come with a library for Arduino?
A: Yes, there are several open-source libraries available on GitHub and the Arduino Library Manager that support the SGP30 sensor.
Q: What is the warm-up time required before reading data?
A: The sensor typically requires about 15 minutes of operation upon first power-up to stabilize, though full baseline calibration takes up to 7 days of continuous operation.
Q: Does this module include pull-up resistors for the I2C lines?
A: Most breakout boards including this module come with onboard pull-up resistors, but please check your specific board layout or schematic to confirm before connecting.
Q: Can this detect carbon monoxide (CO)?
A: No, the SGP30 is designed specifically for Total Volatile Organic Compounds (TVOC) and equivalent Carbon Dioxide (eCO2). It does not directly measure Carbon Monoxide.
