Great for IoT projects
Works perfectly with my ESP32. The I2C library was easy to find and implement. Readings seem consistent with my other monitor.

Perfect for ventilation control
Using this to trigger fans when CO2 levels rise in my grow tent. The I2C connection is stable and the data is useful for automation.

Good sensor, needs warm-up
Quality is solid. Just remember it needs about 10 minutes to warm up before readings stabilize. Good value for the price.

Calibration takes time
The sensor works, but baseline calibration takes a few days of continuous operation. Don't expect instant perfect accuracy out of the box.

Reliable for classroom kits
Bought ten of these for our students. All arrived working. Great for teaching air quality concepts without breaking the budget.
Q: Does it require external humidity data?
A: For best accuracy, feeding external humidity data is recommended, but it can operate standalone.
Q: How long does the sensor last?
A: The typical lifetime is greater than 10 years under normal operating conditions.
Q: What is the default I2C address?
A: The default I2C address is 0x58.
Q: Is there a library for Arduino?
A: Yes, several open-source libraries are available compatible with the SGP30 sensor driver.
Q: Does this detect carbon monoxide?
A: No, the SGP30 is designed for TVOC and eCO2. It is not suitable for detecting carbon monoxide leaks.
