Great for monitoring plant rooms

Using this to monitor CO2 levels in my indoor garden. It helps me know when to activate the exhaust fans. The only downside is it takes a bit of time to stabilize after power-on.

Good sensor, needs warm-up

The sensor provides stable data after the initial warm-up period. Just remember to let it run for a few minutes before trusting the first readings. Documentation could be slightly better, but plenty of examples online.

Excellent sensitivity

I am impressed by how quickly this reacts to changes in air quality, such as cooking fumes or opening a window. The TVOC readings are very responsive. Highly recommended for DIY air monitors.

Easy integration

Used the Adafruit library with this breakout board and it worked out of the box. No calibration issues so far. The form factor is compact and fits well in my custom enclosure.

Perfect for my smart home project

This SGP30 module works flawlessly with my ESP32. The I2C connection was easy to set up, and the eCO2 readings seem quite accurate when compared to a reference meter. Great value for the price.

5 FAQ

Q: What is the I2C address for this module?

A: The default I2C address for the SGP30 sensor is 0x58. This is standard across most manufacturers of this chip.

Q: Does this sensor require external calibration?

A: The SGP30 features an Automatic Baseline Correction (ABC) algorithm that self-calibrates over time when exposed to fresh air regularly. No manual calibration is typically needed for general use.

Q: Can this detect carbon monoxide (CO)?

A: No, this specific SGP30 module is designed to measure Total Volatile Organic Compounds (TVOC) and equivalent Carbon Dioxide (eCO2). It does not directly measure Carbon Monoxide.

Q: How long does the sensor last?

A: Under normal operating conditions, the SGP30 sensor has an expected lifetime of more than 10 years.

Q: Is this compatible with 5V Arduino boards?

A: Yes, the module includes a voltage regulator and level shifting, making it safe to use with both 3.3V and 5V microcontrollers like the Arduino Uno.
