Non-Dispersive Infrared, NDIR, Carbon Dioxide Sensors ...

Carbon dioxide sensors are commonly used in building automation systems to monitor air quality. The level of carbon dioxide is indirectly proportional to the amount of people in a space and can be used to adjust ventilation for the space. There are two basic types of gas sensing technologies: chemical reaction and infrared spectroscopic. Most chemical reaction sensors are electrochemical ...

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 passes through the optical filter. The band of IR ...

IR vs TC: Settling the CO2 sensor debate once and for all ...

2016-07-26· IR sensors, on the other hand, operate on the theory that light is absorbed by gases at specific frequencies. For instance, light is absorbed by CO2 at μm, within the IR band of the electromagnetic spectrum. The sensor measures the IR light directed at the CO2 gas. Other wavelengths are prevented from hitting the sensor via a filter.

CO2 Gas Monitor - RI-600 Series by RKI Instruments

When CO2 enters the gas cell, the amount of infrared energy received by the IR sensor decreases since the infrared energy emitted from the IR source is absorbed by the CO2. This decreased energy is detected by the IR sensor and is displayed as a gas concentration. An optical band pass filter in front of the IR sensor passes the CO2’s absorption wave length. Power options are 115 VAC or 24 ...
