Reliable CCS811 Breakout
Clean board layout. I2C addresses are configurable which is a huge plus for multiple sensors on the same bus.

Great for monitoring
Using this in my greenhouse controller. VOC and CO2 data helps optimize ventilation schedules effectively.

Hard to find libraries
The hardware is fine, but finding compatible libraries for my specific IDE took some time. Documentation could be clearer.

Perfect for IoT Projects
Integrated easily with my ESP32. Readings seem consistent compared to my reference meter. Great value for the price.

Good sensor, patience needed
Works well but requires the initial burn-in time. Once calibrated, data is stable. Would recommend for home automation.
Q: How long does the sensor last?
A: The expected lifespan is typically around 10 years under normal operating conditions.
Q: Does it measure actual temperature or just compensate?
A: It has an internal temperature sensor for compensation, but external compensation is recommended for higher accuracy.
Q: Can I use this outdoors?
A: It is not weatherproof. You would need an enclosure to protect it from rain and dust for outdoor use.
Q: Is this compatible with 5V Arduino boards?
A: Yes, but logic level shifting is recommended as the sensor operates at 3.3V to prevent damage.
Q: What is the default I2C address?
A: The default I2C address is 0x5A, but it can be changed via hardware pins on the module.
