Nondispersive infrared (NDIR) spectroscopy is often used to detect gas and measure the concentration of carbon oxides (for example, carbon monoxide and carbon dioxide). An infrared beam passes through the sampling chamber, and each gas component in the …
Like other infrared sensors, NDIR sensors rely on the principle that a target gas (, CO 2) absorbs a specific band of infrared light while transmitting other wavelengths of light, thus reducing the energy reaching an infrared light detector (Dinh et al., 2016). A challenge with this technology is the need to reduce interference from nontarget gases, such as water vapor, although recent ...
Photodiode (Infrared sensor of NDIR CO2 sensor) Since the photodiode is a photo type detector, its response speed is overwhelmingly faster (typ. 2μs) than that of a thermal type detector. Therefore, by incorporating this photodiode into a NDIR gas sensor and combining with LED of an infrared light emitter, the power consumption can be reduced to the minimum.
