In our daily lives, the importance of Indoor Air Quality is self-evident. Especially for two colorless and odorless gases——Carbon Monoxide (CO) and Carbon Dioxide (CO2), they may pose a threat to our health unknowingly. Therefore, understanding the safety standards for indoor CO and CO2, and how to monitor them, is crucial for protecting our living environment.

Carbon Monoxide is an extremely dangerous gas that can be released from incomplete combustion equipment. According to Chinese national standards, the safe concentration of carbon monoxide in indoor air should be maintained below 9 milligrams per cubic meter (9 ppm). Beyond this concentration, the human body may experience fatigue, headaches, or even more serious poisoning symptoms. Long-term or high-concentration exposure can lead to permanent brain damage or death.

Carbon dioxide is usually produced by human respiration and is a common component of indoor air. In China, the safe concentration of carbon dioxide in indoor air is set at 1000 ppm. When concentrations exceed this standard, it may cause headaches, drowsiness, and lack of concentration. Continuous exposure to high-concentration carbon dioxide environments can also affect human cognitive function and health.

To ensure indoor air safety, using specialized gas sensors to monitor concentrations of carbon monoxide and carbon dioxide is vital. Carbon monoxide sensors can detect CO concentrations in the air in real-time and sound an alarm when dangerous levels are reached. Carbon dioxide sensors can likewise monitor CO2 concentrations, helping us ensure Indoor Air Quality stays within safe limits. Additionally, dust sensors can be used to monitor indoor particulate matter levels, further safeguarding air quality.

In summary, understanding and monitoring the concentrations of indoor carbon monoxide and carbon dioxide is an important part of ensuring the environmental safety of our residences. By using carbon monoxide sensors and carbon dioxide sensors, we can not only identify potential air quality issues in time but also take necessary measures to prevent possible health risks. Therefore, for the health of ourselves and our families, monitoring Indoor Air Quality is an important task that should not be overlooked.
