Compared with other types of gas sensors, infrared gas sensors have a lot of advantages, such as good selectivity, long life, no dependence of oxygen, small interference by the environment, not easy to poison, high accuracy, etc. With the development of sensing technology, more and more advanced infrared gas sensors have appeared on the market.

In actual applications, infrared gas sensors are highly practical. Its application fields are very wide. Whether it is petrochemical, atmospheric monitoring, medical and health, and agricultural development, they have made a lot of contributions. Let’s share the application of infrared gas sensors in specific fields.

1) Infrared gas sensor is used in environmental protection fields like air quality detection

When the infrared gas sensor is used for air quality monitoring, it is mainly aimed at the detection of carbon dioxide concentration in the air. Due to the greenhouse effect, carbon dioxide can absorb infrared rays, and this absorption can be used to measure the carbon dioxide concentration per unit volume.

The principle of infrared carbon dioxide sensors is to weaken the radiation energy transmitted by the measurement room according to the absorption of CO2 in a specific band, and the degree of attenuation depends on the concentration of CO2 in the measured gas.

The use of CO2 sensors can be seen everywhere in our daily environment, such as kindergartens, schools, office buildings, shopping malls, supermarkets, stations, hospitals and other public places.

2) Infrared gas sensor is used in industrial fields like petrochemical and chemicals

In the process of industrial production, there are a variety of flammable and explosive gas and toxic gases. These gases are harmful to the atmospheric environment, on the other hand, they also threaten the physical health of staffs.

Based on various advantages, infrared gas sensors played a very important role in industrial operations such as petroleum, chemical industry, power plant, metallurgical coke. For example, gas detection and carbon dioxide detection with explosion -proof requirements in the industrial environment require infrared gas sensors to help.

3) Infrared gas sensors are used in agriculture, breeding, scientific research and other fields

Both plants and animals are inseparable from air. Agriculture and aquaculture are paying special attention to the concentration value of carbon dioxide gas.

For agricultural planting, the basic elements of green plant growth are carbon dioxide and water. Under the conditions of light, they are photocherated through plant chloroplasts to synthesize carbohydrates and release oxygen. It can be seen that the role and importance of carbon dioxide and water in plant growth are irreplaceable.
