CRIR M1 Digital CO2 Sensor Non Dispersive Infrared 400PPM To 2000PPM Small Size
The CRIR M1 carbon dioxide sensor is a gas sensor based on the principle of non-dispersive infrared (NDIR). It is favored by many instrument manufacturers and equipment integrators due to its small size, high integrability, automatic baseline calibration, temperature compensation and other advantages. This CO2 sensor uses a single-channel design. Infrared light is emitted from a light source at one end, through a filter (blocking wavelengths that are not sensitive to CO2), and on to an infrared detector. The higher the detected light source attenuation, the higher the CO2 concentration in the detected gas path. According to this principle combined with a scientific algorithm, the corresponding CO2 concentration value can be obtained.
