Perfect for my air quality monitor project
This SGP30 module works flawlessly with my ESP32 setup. The I2C communication is stable, and the eCO2 readings seem quite accurate when compared to a reference meter. Great value for DIY enthusiasts.

Compact and reliable
Love how small this module is. It fits perfectly into my custom enclosure. The TVOC response is very sensitive to cooking fumes and cleaning products, which is exactly what I needed for my smart home automation.

Easy integration with Arduino
Used the standard Sensirion library and had it up and running in minutes. The data output is clean and easy to parse. Highly recommend for anyone building environmental monitoring stations.

Exceeded my expectations
Fast shipping and the module arrived well-packaged. The soldering pads are large enough for hand soldering if you don't have a reflow station. Very happy with this purchase.

Good sensor, requires calibration time
The sensor provides consistent data after the initial burn-in period. Make sure to let it run for a few days in fresh air for the baseline to stabilize. Documentation could be slightly better, but overall a solid choice.

Solid performance for the price
It's not a laboratory-grade instrument, but for consumer electronics and hobby projects, it exceeds expectations. The formaldehyde estimation is a nice bonus feature to have on board.
Q: Does this module come with a breakout board or is it just the raw sensor?
A: This listing is for the SGP30 module mounted on a small breakout board with header pins, making it easy to connect to breadboards or microcontrollers via I2C.
Q: What is the expected lifespan of the heater element?
A: The integrated heater is designed for long-term operation. Under normal usage conditions within the specified voltage range, the sensor typically lasts for several years. Continuous operation within datasheet limits is recommended.
Q: Is there a library available for Raspberry Pi?
A: Yes, there are several Python libraries available for the Raspberry Pi that support the SGP30 via the I2C bus. You can find community-maintained packages on GitHub or use the official Sensirion drivers adapted for Linux.
Q: How often should I recalibrate the sensor?
A: The SGP30 features an automatic baseline correction algorithm. However, for best accuracy, it is recommended to expose the sensor to fresh outdoor air (approx. 400 ppm CO2) for at least one hour once every few months if used in a constantly sealed environment.
Q: Can this sensor detect carbon monoxide (CO)?
A: No, the SGP30 is specifically designed for TVOC and eCO2 (equivalent CO2) estimation. It does not directly measure Carbon Monoxide (CO). Please look at our SGPC3 or other specific CO sensors for that application.
