Fast Response Time
Impressed with how quickly the sensor detects changes in air quality when cooking or cleaning. The AHT20 temp sensor is a nice bonus.

Good Accuracy After Calibration
Works well once you let it run for a few days to calibrate. Initial readings were a bit off, but stabilized quickly. Would recommend for indoor monitoring.

Perfect for ESP32 Projects
Integrated this module into my smart home dashboard. The I2C connection was straightforward and the data readings are consistent. Great value for the price.

Documentation Could Be Better
The hardware works fine, but finding the right library took some searching. Once set up, it functions as described. Just wish there was a clearer guide.
Q: Can I use this sensor outdoors?
A: This module is not waterproof or weatherproof. It is designed for indoor air quality monitoring applications only.
Q: Is there an Arduino library available for this sensor?
A: Yes, there are several open-source libraries available on GitHub compatible with Arduino and ESP32 platforms.
Q: How long does the initial calibration take?
A: For best accuracy, we recommend running the sensor in a well-ventilated area for 24 to 72 hours during initial setup.
Q: Does this module have a built-in voltage regulator?
A: Yes, the module includes an LDO regulator allowing you to power it with either 3.3V or 5V logic safely.
Q: What is the difference between CO2 and eCO2 on this module?
A: This sensor calculates equivalent CO2 (eCO2) based on VOC measurements. It is an estimation for air quality, not a direct NDIR CO2 measurement.
