Le taux de CO2 normal dans l''air est de 350 à 450 ppm. Le CO2 est un gaz inodore, incolore et ininflammable. Le CO2 a pour particularité d''absorber certaines fréquences infrarouges. Les nouveaux modèles de capteur utilisent donc des cellules infrarouges pour la mesure du taux de CO2. D''autres versions de capteurs existent.

Study about different Gas Analyzers Interview Questions and answers like NDIR analyzers, H2S Analyzer, Moisture Analyzer, HCDP Analyzer, CO2 Analyzer.. Gas Analyzers Questions What is a Gas Analyzer? Gas Analyzer is an instrument used to measure the concentration of a known gas in given mixture of gases from a process / stream.
NDIR sensors are the most reliable method for detecting carbon dioxide gas. NDIR sensors are based on infrared spectroscopy, the principal that molecules absorb specific light frequencies that are characteristic of their structure. When the frequency of the infrared light is the same as the vibration frequency of a bond, absorption occurs.
Using carbon dioxide (CO2) monitors. People exhale carbon dioxide (CO2) when they breathe out. If there is a buildup of CO2 in an area it can indicate that ventilation needs improving. Although CO2 levels are not a direct measure of possible exposure to COVID19, checking levels using a monitor can help you identify poorly ventilated areas.
Oct 09, 2016· The UART readings at least make sense. Normal CO2 concentrations at open spaces should be around 400ppm, and a room may well be around 650ppm. While calculating ppm2, since you defined tl=1004th I think that (th+tl4) will always be 1000, so you can use ppm2=2(th2) I''m quite sure that there are two versions of this sensor.
