Non-dispersive infrared (NDIR) sensors are relatively simple optical devices consisting of an IR source, a gas sample, and a detector (see figure 1). The presence of a wavelength selective optical filter situated in front of the detector is a key component in determining the gas to be detected. Figure 1: Illustration of NDIR gas detection system

When measuring gases like carbon dioxide, oxygen, or methane, the term concentration is used to describe the amount of gas by volume in the air. The 2 most common units of measurement are parts-per-million, and percent concentration. Parts-per-million (abbreviated ppm) is the ratio of one gas to another. For example, 1,000ppm of CO2 means that if you could count a million gas molecules, 1,000 ...
