Carbon dioxide sensors for indoor air quality monitoring

The importance of indoor air quality monitoring has three key points

The importance of indoor air quality monitoring is demonstrated by maintaining people's health, improving work and learning efficiency, and promoting environmental sustainability. By monitoring indoor air quality, we can create a healthier, more efficient and sustainable indoor environment.

（1）Primarily, indoor air quality is directly related to people's health. Since we spend most of our time indoors, airborne pollutants may cause damage to our respiratory and immune systems. Through monitoring, we can detect and solve potential air pollution problems at an early stage to safeguard the health of residents.

（2）Moreover, indoor air quality monitoring is crucial to enhancing work and study efficiency. Studies have shown that an environment with good indoor air quality can improve people's concentration and focus, thus enhancing their work and study efficiency. By monitoring and controlling indoor air quality, we are able to provide better working and learning environments for employees and students, enhancing productivity and learning.

（3）Lastly, indoor air quality monitoring also plays an important role in environmental sustainability. Nowadays, people are paying more and more attention to environmental protection and sustainable development. By monitoring indoor air quality, we can understand and control pollutants in the indoor environment, reduce the negative impact on the environment and promote sustainable development.

Indoor air quality monitoring application scenarios are diverse

1. First of all, it is the residential environment. Indoor air quality monitoring can help residents find and solve potential pollution problems, such as formaldehyde and carbon dioxide, in time to provide a healthier living environment.

2. And next is the office environment. By monitoring indoor air quality, it can improve the efficiency and health of employees, thus enhancing the quality of the entire office environment.

3. Finally, public places. Monitoring indoor air quality can improve the air quality in public places such as schools, hospitals, shopping malls, etc. and protect the health of the people.

Relationship between indoor carbon dioxide concentration and air quality

Indoor carbon dioxide concentration is one of the most important indicators of indoor air quality. 

When the carbon dioxide released from human respiration accumulates to a certain concentration, it will cause the indoor air to become stuffy and hypoxic, and may trigger uncomfortable symptoms such as dizziness and fatigue. 

Therefore, the monitoring of indoor carbon dioxide concentration can remind people to ventilate in time to keep the indoor air fresh.

How Carbon Dioxide Sensors Work in Indoor Air Quality Monitoring

Carbon dioxide sensors work by sensing carbon dioxide molecules in the surrounding environment and converting them into an electrical signal. 

The chemical material in the sensor traps the surrounding carbon dioxide molecules and triggers a change in the internal charge, which generates an electric current. 

By measuring the change in current, the sensor can accurately measure the concentration of carbon dioxide in the room. This principle of operation allows the CO2 sensor to quickly and accurately monitor indoor air quality and provide real-time data for user reference.
