WebAug 5, 2024 · CO2 sensors that measuring CO2 levels from 400ppm (fresh air) to over 3,000ppm (stuffy office) are used for indoor air quality. Therefore, CO2 sensors that measure in the range of 400ppm to 10,000ppm are typically used in HVAC applications. WebJun 1, 2024 · Carbon dioxide meters use NDIR, an infrared absorption technology that detects CO2 molecules. These molecules absorb radiation, which changes the light transmission intensity between an infrared source and detector. This change is analyzed by a photodetector which then outputs a voltage signal proportional to the CO2 concentration. WebHow does optical dissolved oxygen work? The sensing element for an optical DO sensor is an oxygen sensitive luminophore. A blue light from the sensor excites the luminophore. When the excited molecule returns to its ground state it gives off red light. In the presence of oxygen some of the energy is transferred to the oxygen molecule. iphone6s 分辨率
