Co2 Gas Sensor Working

A carbon dioxide sensor or co 2 sensor is an instrument for the measurement of carbon dioxide gas.

Co2 gas sensor working. A chamber containing small living things such. The sensor has two ranges. Ndir is an industry term for nondispersive infrared and is the most common type of sensor used to measure carbon dioxide or co2. Normally the atmosphere will contain more oxygen than combustible gases.

The vernier co 2 gas sensor measures gaseous carbon dioxide levels by monitoring the amount of infrared radiation absorbed by carbon dioxide molecules. The ability of a gas sensor to detect gases depends on the chemiresister to conduct current. Md62 gas sensor consists of an active element and a reference element with the same resistance both elements are placed in a wheatstone bridge circuit. Winsen electronics produces co2 gas sensor md62 using thermal conductor working principle for industrial spot co2 detection.

The most common principles for co 2 sensors are infrared gas sensors 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 industrial processes. Low 0 10 000 ppm and high 0 100 000 ppm. The co2 gas sensor measures gaseous carbon dioxide in two ranges 0 to 10 000 ppm and 0 to 100 000 ppm.
