Use range of carbon dioxide sensor

The carbon dioxide sensor is mainly used to measure the carbon dioxide composition in the atmospheric environment, which has an important impact on every field. With the continuous progress of modern society, the carbon dioxide content also gradually increases. Too high a carbon dioxide content component will produce our bodies. Serious impact, but also threaten the environment on which we depend.

Carbon dioxide sensor is a kind of gas sensor, which mainly detects carbon dioxide gas concentration and so on. Carbon dioxide sensors are widely used in industry, animal husbandry, agriculture and public places. Here is a brief introduction:

1. Industry

Carbon dioxide gas sensors are more widely used in industry, such as wastewater treatment, safety production and other industries, especially when underground operations are required to monitor carbon dioxide concentration. Carbon dioxide gas sensors are also commonly used in carbon dioxide-related industries such as metal processing, pulp and paper, cleaning and solvent extraction, and low-temperature cleaning.

2. Animal husbandry

The air quality of the barn of the farm is related to the healthy growth of the animals. If animals live in turbid air for a long time, where the concentration of carbon dioxide is high, and there is no ventilation, it will cause the animal to become sick or cause an epidemic. A carbon dioxide gas sensor is installed in the livestock house, which can monitor and warn the carbon dioxide concentration at any time and remind to ventilate, which is conducive to the healthy growth of animals.

3. Agriculture

Carbon dioxide is related to plant photosynthesis, and therefore plant output. Proper concentration of gas fertilizer can increase the yield of agricultural crops. Application of carbon dioxide gas sensor in agriculture, when the concentration of carbon dioxide is insufficient, can remind the use of gas fertilizer, whether it is for the growth of vegetable plants or to increase the yield of vegetables, it is of great help. Many greenhouse cultivation this year are equipped with carbon dioxide gas sensors To detect the concentration of carbon dioxide in the greenhouse.

4. Public places

In places where people are dense, such as office buildings, meeting rooms, classrooms, hotels, exhibition halls, hospitals, shopping malls, bars, restaurants, airports, train stations, entertainment halls, theaters, etc., carbon dioxide gas sensors can be installed for ventilation control and environment Quality monitoring is conducive to human physical and mental health.

Now, the carbon dioxide gas sensor has been integrated into all aspects of our lives. With the enhancement of human awareness of the environment, its scope of application will be further expanded.

Installation height of carbon dioxide sensor

The installation height of the carbon dioxide sensor is about 1 meter 5 and the test combination of the infrared carbon dioxide monitor is related to the poster. Generally, the results can be calibrated according to the altitude.

As the greenhouse effect continues to intensify, people are paying more and more attention to the concentration of carbon dioxide in the air, so the application field of carbon dioxide sensors is also more and more extensive. When using carbon dioxide sensors, they must be installed first, and carbon dioxide The installation of the sensor is directly related to the accuracy of the measurement, so what needs to be paid attention to when installing the carbon dioxide sensor?

When installing the carbon dioxide sensor, it must not be installed where people directly exhale to the carbon dioxide sensor, close to the intake or exhaust duct, or close to the window and door.

1. When installing the carbon dioxide sensor, the wall-mounted sensor should be preferred, and the use of the tube-mounted sensor should be avoided as much as possible, because the wall-mounted carbon dioxide sensor can provide more accurate CO2 information for the effectiveness of the ventilation system.

2. The wall-mounted carbon dioxide sensor should be installed 1–6 feet (0.3–1.8 meters) from the floor.

3. The tube-mounted CO2 sensor is more suitable in a single-zone system, but it should be installed as close to the actual occupied space as possible, so that maintenance will be more convenient.

4. For multiple roof installations, it is better to install a carbon dioxide sensor in each area; and for a system with variable ventilation, install a carbon dioxide sensor in each main area.

5. For fixed-volume single-roof installations used in multiple areas, it is recommended to install a sensor for each area or space, and perform ventilation control based on the maximum carbon dioxide content reading.

6. For a common area with multiple VAV boxes, if the occupied space is evenly distributed throughout the common area, a single carbon dioxide sensor can also be used.
