Good Value Sensor
Works well for the price. Documentation could be slightly more detailed regarding the I2C address configuration, but overall satisfied.

Compact Design
Fits perfectly in my custom enclosure. The footprint is small enough for portable air quality logging projects.

Accurate CO2 Readings
Compared it against a reference meter in my office. The CO2 levels matched closely. Great for monitoring ventilation needs.

Excellent for Home Automation
Integrated this into my smart home system easily. The UART communication is stable and the readings seem consistent with my standalone meter.
