About this item
- 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.
- The complete kit is the whole parts list as a single item: we collect every part, check it and ship the set together, so nothing is missing when you sit down to build.
- Prefer to buy only some of the parts?
- The project page lists every part with its own price, and you can add just the ones you need.
