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.
· Infrared CO 2 sensors use infrared light to detect the amount of CO 2 in the chamber. This type of sensor is more expensive but more accurate. In this post, we’ll explain these two types of sensor in more detail and discuss the practical implications of each. Thermal Conductivity. Thermal conductivity works by measuring electrical resistance through the atmosphere. The sensor will typically ...
· IR Sensors. 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. Higher CO2 levels would cause fewer IR rays to pass through the filter and be detected by the sensor. Low CO2 …
· We clearly understand that CO2 incubators maintain specific levels of CO2, temperature, and humidity for optimum cell growth. These parameters are monitored and controlled via sensors. As for CO2, there are two types of CO2 sensors commonly found in incubators: the TC (thermal conductivity) sensor and the IR (infrared) sensor. But which one is better…

Measuring Carbon Dioxide (CO2) Using Non-Dispersive Infared (NDIR) Technology NDIR sensors work using spectroscopy, which pertains to the dispersion of light into its component colors or energies. An example of this is light in the Visible Spectrum (the light humans can see), which is made up of a wide range of wavelengths (~390nm-700nm).
NDIR CO 2 sensors are also used for dissolved CO 2 for applications such as beverage carbonation, pharmaceutical fermentation and CO 2 sequestration applications. In this case they are mated to an ATR (attenuated total reflection) optic and measure the gas in situ. New developments include using microelectromechanical systems (MEMS) IR sources to bring down the costs of this sensor and to ...

Use Infineon’s XENSIV TM PAS CO2 sensor to track the environment you are in – for improved health, productivity and overall well-being. Increasingly efficient building insulation can help to mitigate the effects of climate change, but heavily-insulated buildings are not always good for human health. Poor ventilation can result in lower oxygen levels and a build-up of carbon dioxide (CO 2 ...
Because the sensor operates on the basis of reading IR radiation, you should avoid using the sensor in direct sunlight as much as possible. Even though the IR detector is shielded, it is best to avoid the possibility of reflected light affecting the readings by keeping the sensor in the shade when used outdoors. Best results are obtained when only one CO 2 Gas Sensor is connected to an ...
Infrared light is used to directly detect CO 2 A commonly used basic infrared sensor, shown in Figure 1, was introduced for the Thermo Scientific™ Forma™ CO 2 models in 1988. It consists of an incandescent bulb producing light including in the infrared band, a sample chamber, an interference filter and an IR …
