CO2 sensor (carbon dioxide concentration measuring device)

A compact CO2 sensor that displays carbon dioxide (CO2) concentration in real-time. It visualizes indoor carbon dioxide levels at one-second intervals.

When the indoor CO2 concentration reaches 10,000 ppm, cognitive ability and concentration decrease. As CO2 levels rise, symptoms such as fatigue, drowsiness, humidity, and indoor air quality issues occur. The indoor carbon dioxide concentration is visualized at one-second intervals, making it easy to see when ventilation is needed.
