Co2 Gas Sensor Working

The co2 gas sensor measures gaseous carbon dioxide in two ranges 0 to 10 000 ppm and 0 to 100 000 ppm.

Co2 gas sensor working.

A carbon dioxide sensor or co 2 sensor is an instrument for the measurement of carbon dioxide gas. The most commonly used chemiresistor is tin dioxide sno2 which is an n type semiconductor that has free electrons also called as donor. The sensor has two ranges. Students can use the co 2 gas sensor to measure the change in carbon dioxide levels for a variety of systems including.

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. Low 0 10 000 ppm and high 0 100 000 ppm. Winsen electronics produces co2 gas sensor md62 using thermal conductor working principle for industrial spot co2 detection.

Ndir is an industry term for nondispersive infrared and is the most common type of sensor used to measure carbon dioxide or co2. A chamber containing small living things such. 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.
