As a key indicator of indoor air quality, carbon dioxide concentration directly affects human health and comfort. The CO2 sensor, as a modern monitoring tool, can track indoor CO2 levels in real-time, providing a safeguard for healthy breathing.

Most common indoor CO2 sensors utilize Non-Dispersive Infrared (NDIR) technology. This technology exploits the specific infrared light absorption characteristics of CO2 molecules. Specifically, an NDIR sensor consists of an infrared light source, a detector, and a gas sample cell. The light source emits infrared light at a specific wavelength; as it passes through the sample cell, it is partially absorbed by CO2 molecules. The detector measures the remaining light intensity and converts it into an electrical signal to calculate the concentration.

Key features of these products include:

● High Precision: Accurately measures indoor CO2 levels to assess air quality.

● Fast Response: Promptly detects concentration changes, providing timely data support for adjustments.

● Excellent Stability: CO2 sensors typically offer long service lives and stable performance.

● Easy Installation & Maintenance: Compact size and low power consumption make them easy to deploy.

● Wide Application: Suitable for homes, offices, schools, and various other indoor environments.

With advancing technology and decreasing costs, CO2 sensors are set to become a household essential for a healthier lifestyle.
