Excellent sensitivity
Very sensitive to changes in air quality. I can detect when someone starts using hairspray or alcohol cleaner instantly. The build quality of the breakout board is solid too.

Reliable and accurate
Integrated this into a smart office dashboard. The data output is clean, and the sensor recovers quickly after exposure to high VOC events. Highly recommended for IoT developers.

Good sensor, needs burn-in time
The sensor quality is excellent, but remember it needs about 48 hours of continuous power to stabilize fully. Once burned in, the TVOC readings are quite responsive to cooking smells and cleaning products.

Perfect for Home Automation Projects
This SGP30 module works flawlessly with my ESP32 setup. The I2C communication is stable, and the eCO2 readings seem very consistent compared to my reference meter. Great value for the price.

Essential for my greenhouse monitor
I used this to monitor air quality in my small greenhouse. It helps me know when to ventilate based on CO2 levels. The library support for Arduino is robust and easy to implement.

Great upgrade from older models
Upgraded from an MQ series sensor, and the difference in precision is night and day. The only minor issue is that the pinout wasn't clearly labeled on the back, but the datasheet helped.
Q: How do I reset the baseline if I move the sensor to a new location?
A: You can reset the baseline by sending the specific I2C command defined in the Sensirion datasheet or by using the 'setBaseline' function in most standard libraries with fresh air values.
Q: Does this module require external pull-up resistors for I2C?
A: Yes, this breakout board includes built-in pull-up resistors, so you can connect it directly to your microcontroller without needing external components.
Q: Is there a Python library available for Raspberry Pi?
A: Yes, several community-maintained libraries exist for Python on Raspberry Pi, such as 'sgp30-python' available via pip, which simplifies integration.
Q: Can this sensor 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 detect Carbon Monoxide.
Q: What is the warm-up time before readings are accurate?
A: While initial readings appear within seconds, the sensor requires approximately 48 hours of continuous operation to fully stabilize and provide highly accurate baseline measurements.
