Needs careful handling
Sensor is sensitive to soldering heat. Follow the reflow profile strictly or it might get damaged. Works fine otherwise.

Perfect for IoT Projects
Integrated easily with my ESP32 setup. The I2C communication is stable and the readings seem consistent with professional equipment.

Great support documentation
The datasheet is clear and the driver libraries available online made integration straightforward. Highly recommend for air quality monitors.

Compact and Reliable
Very small footprint which saved space on my PCB. Power consumption is low enough for battery-operated devices.

Good accuracy after warm-up
Works well once the initial calibration period is over. Make sure to let it run for a few days for best eCO2 accuracy.
Q: What is the expected lifespan of the sensor?
A: Under normal operating conditions, the sensor has a lifespan of approximately 10 years.
Q: Does humidity affect the readings?
A: The sensor has built-in compensation for humidity, but extreme conditions outside the operating range may impact accuracy.
Q: Is this compatible with 5V Arduino boards?
A: Yes, but you need a logic level converter since the sensor operates at 1.8V to 3.6V. Do not connect directly to 5V GPIO pins.
Q: How long does the initial calibration take?
A: The sensor performs auto-calibration over time. For best eCO2 accuracy, we recommend running it in a well-ventilated area for at least 7 days.
Q: Can this detect carbon monoxide?
A: No, this module measures TVOC and eCO2. It is not designed for detecting specific dangerous gases like Carbon Monoxide.
