ESP32 Project 14: Home CO₂ Monitoring System

ESP32 + SCD41 + R1BBIT

In just 10 minutes, you can build a useful, fully functional project that measures CO₂ levels, temperature, and humidity in your room.

The data is available in the terminal, in widgets on your PC or Mac, and in the iOS and Android mobile apps.

The code is so compact that it’s hard to believe!
