Carbon dioxide - Wikipedia

Carbon dioxide (chemical formula CO 2) is an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. The current concentration is about % (412 ppm) by volume, having risen from pre-industrial levels of 280 ppm. Natural ...

Performance of interdigitated capacitive-type CO2 sensor ...

· Mojtaba et al. studied a capacitive carbon dioxide sensor operated at room temperature based on a dielectric nanocomposite comprising P-type multi-walled carbon nanotube. They found that adding a small amount of P-type multi-walled carbon nanotube in diphenylethylenediamine can dramatically improve the CO 2 sensitivity . Venkateswarlu et al. investigated the open metal site metal …

Carbon Dioxide Sensor - Sensors Development

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.
