CO2 Sensor - Infineon Technologies

Poor ventilation can result in lower oxygen levels and a build-up of carbon dioxide (CO 2). ... Pulses of light from an infrared source pass through an optical filter tuned specifically to the CO 2 absorption wavelength (λ= µm). The CO 2 molecules inside the measurement chamber absorb the filtered light, causing the molecules to shake and generate a pressure wave with each pulse. This is called the …

How does an NDIR CO2 Sensor Work? |

NDIR is an industry term for " nondispersive infrared ", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector. The IR light detector measures the amount of IR light that ...
