Carbon Dioxide Sensor - Sensor Technology | Sensors ...

The carbon dioxide gas sensor measures gaseous carbon dioxide levels by detecting the quantity of IR radiation absorbed by carbon dioxide molecules. The sensor employs a hot metal filament that acts as an IR source to generate IR radiation. The IR source is located at one end of a sensor tube, and another end is provided with an IR sensor.

Testing the MH-Z19 Infrared CO2 Sensor Module • Circuits

2017-06-30· The non-dispersive infrared (NDIR) carbon dioxide sensors rely on an infrared light source and detector to measure the number of CO 2 molecules in the sample gas between them. Over many years, both the light source and the detector deteriorate, resulting in slightly lower CO 2 molecule counts. To combat sensor drift, during calibration a sensor …

CO2 Sensors Products |

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.

How UV, IR and Imaging Detectors Work - Sensor Technology

An IR detector is a pyroelectric sensor that is capable of detecting thermal radiation and is rather sensitive to variations of the received light signal. A tantalum/lithium crystal is associated with an OP amp or a field-effect transistor. An optical filter (a spectral gate) chooses a specific spectral band or wavelength ( µm, µm, 4 to 5 µm…).

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

A basic NDIR sensor consists of an infrared light source, a sample chamber, an infrared filter, and infrared detector. For carbon dioxide sensing, room or duct air is allowed to flow in and out of the sample chamber. Infrared light waves are created by the source and sent through the sample chamber to the detector. As the infrared light passes through the air in the chamber, light of a ...
