CO2<800 ppm is smart
Solder this to an esp32c3, get Sensirion’s sketch from GitHub, make a handy co2 sensor. Make sure scl and sda are the right pins. I make the led flash when air is too stuffy.

Works well
I used it with ESPHome and an ESP32 dev kit. It needs a stable 3.3V power supply otherwise the sensor disconnects sometimes. Make sure to turn off auto calibration. It usually takes couple minutes after startup to stabilize temperature and humidity.

Great little sensor
Make sure you read the documentation. By default it re-calibrates weekly, taking the lowest measurement as the reference. Depending on your environment, that may seldom go below 500-600ppm (or more!).
