Carbon dioxide is produced by both natural processes (such as respiration and volcanic eruptions) and human activities (such as fossil fuel use and deforestation). Carbon dioxide (CO2) is a product of many natural processes and is a natural and necessary component of our environment.
Under normal circumstances, atmospheric and internal carbon dioxide concentrations do not pose a health risk. Carbon dioxide is essential for respiration, and everyone naturally produces and emits it during breathing. Normal atmospheric carbon dioxide concentrations are approximately 0.04% (400 ppm), a level considered harmless.
The harm of CO2 to humans
Low concentrations of carbon dioxide are not dangerous. However, high concentrations can reduce oxygen levels, negatively impacting humans. Outdoor carbon dioxide concentrations typically range from 350-450 ppm. However, if people are in a closed, unventilated room, carbon dioxide can accumulate.
Moderate carbon dioxide concentrations can cause fatigue, impair cognitive function, and lead to headaches. Studies have shown that even a moderate increase in carbon dioxide concentration from 600 ppm to 1000 ppm can reduce cognitive and decision-making abilities.
Crowded classrooms, crowded meeting rooms, bedrooms, and cars are all prone to high carbon dioxide concentrations. For example, in a bedroom where two people sleep for eight hours without ventilation, carbon dioxide concentrations can rise to 4000 ppm overnight. In a closed classroom, carbon dioxide concentrations can reach 3000 ppm during a 60-minute class, double the current standard of 1500 ppm for elementary and secondary schools. In cars with tightly closed windows, carbon dioxide levels often exceed 3000 ppm and continue to rise.
When there are 5 people in the car, the accumulated carbon dioxide concentration in the car will be even more significant, reaching 10,000 ppm in just 28 minutes!
This demonstrates the crucial role of automotive CO2 sensors in improving ride comfort and driving safety. They monitor in-car CO2 concentrations in real time, enabling air circulation and enhancing comfort. They also detect R744 refrigerant leaks, preventing them before they occur. Furthermore, they can monitor for residual life within the vehicle, ensuring driver and passenger safety.
The MGC20-CO2 vehicle CO2 sensor adopts the dual-channel NDIR gas measurement principle, uses a lightweight metal gas chamber and a high-precision sampling circuit, and can accurately measure the gas concentration of CO2 in the vehicle environment.
