CO Sensor | Carbon Monoxide Detection | Carbon Monoxide ...

· Primarily because it detects the presence of CO which can prevent carbon monoxide poisoning. The gas is tasteless, odourless, and colourless, and therefore it cannot be detected by vision or smell, which makes a CO sensor vital. Carbon monoxide poisoning is the result of breathing in excessive levels of CO. It can cause loss of consciousness, seizures or even death. It is quite …

Carbon Dioxide Detectors & Meters | Edaphic Scientific

Our range of Non-Dispersive Infra-Red (NDIR) CO2 sensors were found to have a 1:1 relationship when compared with an independent measure of carbon dioxide. The CO2 sensor inside of our CO2 detectors is based on Non-Dispersive Infra-Red (NDIR) technology. NDIR is a low cost approach to measuring carbon dioxide for indoor air quality (IAQ) and ...

How to Measure CO2 Application Note - Vaisala

CO 2 detector are light source, measurement chamber, interference filter, and IR detector. IR radiation is directed from the light source through the measured gas to the detector. A filter located in front of the detector prevents wavelengths other than that specific to the measured gas from passing through to the detector. The light intensity is detected and converted into a gas concentration ...

Carbon dioxide sensor - Wikipedia

CO2 gas sensors are available in a number of ‘ppm detection ranges’. They utilize non-dispersive infrared (NDIR) to detect the presence of the gas. CO2 molecules absorb specific wavelengths of light and this is detected in the sensor. Heating and ventilation systems (HVAC) use these to provide demand controlled ventilation (DCV).

How UV, IR and Imaging Detectors Work - Sensor Technology

The combined UVIR detector using a performant UV sensor is limited in terms of detection range (a distance of detection), by the infrared part. The IR sensor is curbed to keep a “reasonable” activation of the IR chain by the surrounding thermal background. By using extra information in the IR band, via a second sensor, this increases the gain of the amplification chains of the detector and ...

Where should I place a carbon monoxide detector? | US EPA

· Where Should I Place a Carbon Monoxide Detector? Because carbon monoxide is slightly lighter than air and also because it may be found with warm, rising air, detectors should be placed on a wall about 5 feet above the floor. The detector may be placed on the ceiling. Do not place the detector right next to or over a fireplace or flame-producing ...
