CO₂ air-quality monitor for classrooms
IntermediateBuild time 2 hours· You'll learn: ESP32, I2C sensors, Data logging
Stuffy classrooms and offices make people drowsy: CO₂ is the number that shows it. The SCD-41 measures real CO₂ (not an estimate), plus temperature and humidity. The ESP32-C3 shows the level on an OLED, lights green, amber or red, and logs it over Wi-Fi so you can see how the air changes through the day.
