is carbon dioxide, I believe everyone is familiar with it, because it is one of the main components in the air after all, but the increase of carbon dioxide will not only cause global warming, but also have a great impact on our daily life. For example, in sheds and greenhouses, too high or too low carbon dioxide will affect the growth of plants or crops. In the office and at home, excess high concentration of carbon dioxide will also affect human health; when the concentration of carbon dioxide reaches more than 1%, it will make people dizzy; when it reaches 4-5%, people will have nausea, vomiting and poor breathing; more than 10%, people will die. Therefore, the carbon dioxide detector measures the indoor air quality. If there is an abnormality, it will trigger an alarm or start the ventilation system when the limit value is exceeded to ensure that the carbon dioxide concentration in the air is within a safe range. Then you know carbon dioxide detector how does it work? The following Yi Yuntian Xiaobian for you to introduce:

br working principle of carbon dioxide detector:

The carbon dioxide gas in the field environment is detected by the absorption principle of the infrared light source.

usually sucks the measured gas into a measuring chamber, and one end of the measuring chamber is equipped with a light source and the other end is equipped with a filter and a detector. the function of the filter is to allow only light of a specific wavelength to pass through, and the detector measures the light flux passing through the measuring chamber, the luminous flux received by the detector depends on the concentration of the measured gas in the environment.

The carbon dioxide detector uses a dual-beam, dual-wavelength infrared detector, which makes the instrument more accurate in the detection process, improves the resolution of the instrument, and has strong stability. The instrument has wind carbon dioxide, temperature and other detection functions, the instrument is provided with a standard gas interface, can be very convenient for instrument calibration, the instrument is provided with a RS-232 interface can be connected with a computer for data processing.

In summary, it is the introduction of the working principle of the carbon dioxide detector.Now, with the increasingly stringent requirements for carbon dioxide content in production operations, carbon dioxide detectors have become an indispensable equipment in various industries, and have been widely used in breeding, agricultural greenhouses, pharmaceuticals, municipal administration, sewage treatment and other fields., Has become an indispensable protective equipment in industrial safety production.
