Perfect for ESP32 Projects
Integrated smoothly with my Home Assistant setup. Readings seem consistent after the initial burn-in period. Great for monitoring indoor ventilation needs.

Reliable Air Quality Monitoring
Using this to trigger my exhaust fan automatically. The I2C connection is stable and libraries are readily available for most platforms.

Compact and Effective
Small footprint fits nicely in my custom enclosure. Detects cooking odors and ventilation needs effectively without being too bulky.

Good sensor, needs patience
Works well but you need to let it run for a few days to get accurate baseline data. Otherwise, good value for the price point.

Initial readings vary
Took a while to stabilize. Once calibrated, it works fine. Just don't expect instant accuracy out of the box without running it first.
Q: Does this detect carbon monoxide?
A: No, this sensor measures TVOC and equivalent CO2, not actual Carbon Monoxide (CO).
Q: Is this suitable for industrial safety?
A: No, this is designed for indoor air quality monitoring and hobbyist projects, not safety-critical alarms.
Q: What library should I use?
A: We recommend the Adafruit SGP30 library or the official Sensirion driver for best compatibility.
Q: How long does calibration take?
A: The sensor learns over time. Initial warm-up is 10s, but baseline accuracy improves over 7 days of operation.
Q: Can I power this with 5V?
A: Yes, the module includes a regulator and is safe for 3.3V and 5V logic power.
