Miniature Sensors Can Detect Potential Dangers of CO2 ...

Jun 11, 2020· CO2 concentration in fresh air is about 400 parts per million (ppm). But get a group of people packed in a closed indoor space, and CO2 concentration can rise quickly. Recent studies suggest that as levels increase above 1,000 ppm, decision-making and other cognitive abilities decline. Roya Maboudian studies the properties of nano-materials, including how their surfaces affect their …

Carbon dioxide sensor - Wikipedia

A carbon dioxide sensor or CO2 sensor is an instrument for the measurement of carbon dioxide gas. The most common principles for CO 2 sensors are infrared gas sensors ( NDIR) and chemical gas sensors. Measuring carbon dioxide is important in monitoring indoor air quality, the function of the lungs in the form of a capnograph device, and many ...

Nondispersive infrared sensor - Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is non-dispersive in the fact that no dispersive element ( a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.

How to calibrate a CO2 sensor? - Yoctopuce

May 01, 2015· Zero calibration of the Yocto-CO2. To circulate the gas into the sensor, set a small tip with a external diameter in one of the two openings on top of the sensor, as is the above picture. Circulate the gas at a litre/min speed for about two minutes, that is one minute more than the time necessary for the measure to stabilize.
