Why do I have CO2 sensor failure, but don't have one ...

If yes continue to the next step, If no replace the RTEM and jump to end. 3. It looks like you do have a CO2 sensor installed. Check DC voltage across the two DCV pins (with wires still attached). If you measure 0VDC (short) or 10VDC (open) then you should verify proper wiring. If wiring is correct then replace the CO2 sensor.

Complete Gas Sensor Circuit Using Nondispersive Infrared ...

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 sample absorbs some particular frequency of infrared. By measuring the amount of absorbed infrared at the appropriate frequency, …

How does an NDIR CO2 Sensor Work? |

As the IR light passes through the length of the tube, the CO2 gas molecules absorb the specific band of IR light while letting other wavelengths of light pass through. At the detector end, the remaining light hits an optical filter that absorbs every wavelength of light except the wavelength absorbed by CO2 molecules in the air sample tube.

User Manual - ETCO2 Sensor | Cables and Sensors

The ETCO2 sensor uses an infrared absorption (IR) technique for monitoring CO2. The principle is based on the fact that CO2 molecules absorb infrared light energy at specific wavelengths, with the amount of energy absorbed being directly related to the CO2 concentration. When the IR light beam is passed through a gas sample containing CO2, an electronic signal from the photodetector can be ...
