Excellent for IoT Projects
Integrated seamlessly with my ESP32 setup. Readings seem consistent and the I2C connection is stable.

Accurate and Compact
Perfect size for my portable air monitor build. Power consumption is low enough for battery operation.

Good Sensor
Requires some calibration time but works well afterwards. Documentation could be clearer for beginners.

Sensitive to Environment
Works okay but needs humidity compensation for best accuracy. Readings drifted slightly in high humidity.

Great Value
Much cheaper than buying the bare chip and easier to solder. Pins are labeled clearly on the PCB.
Q: Do I need a separate humidity sensor?
A: It is recommended to provide humidity data for compensation algorithms to improve accuracy.
Q: Does it detect carbon monoxide specifically?
A: No, it measures Total Volatile Organic Compounds (TVOC) and equivalent CO2, not specific CO.
Q: Is this compatible with 5V Arduino boards?
A: Yes, it operates between 3.3V and 5V, but ensure logic levels are managed if using 5V SDA/SCL lines.
Q: How long does the initial calibration take?
A: Approximately 7 days of continuous operation is recommended for the algorithm to fully calibrate.
Q: Is there a library available for this module?
A: Yes, please check the official Sensirion GitHub repository for Arduino and embedded libraries.
