How does an NDIR CO2 Sensor Work? |

January 05, 2021 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.

Carbon Dioxide Sensor - Sensor Technology | Sensors ...

Indoor and outdoor air has between 400ppm and 2,000ppm CO2 by volume. This means that for projects from measuring indoor air quality to measuring atmospheric CO2, a 0-1% (0-10,000ppm) CO2 sensor is your best solution. For applications like CO2 alarms in restaurants, breweries, or around stored CO2 tanks, a 5% CO2 sensor is used.

Basic Principle of NDIR Gas Detection - Heimann Sensor

IR radiation with µm is not absorbed by either CO2 or other common gases in the atmosphere and is transmitted without loss to the detector. Therefore, it is well suited as reference with no absorption. IR radiation with µm wavelength is only absorbed by CO2 molecules and by no other gases in the atmosphere. This means, that the degree of radiation reduction on that channel depends ...

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.
