Complete Gas Sensor Circuit Using Nondispersive Infrared ...

Carbon dioxide has a very strong absorption band between 4200 nm and 4320 nm, as shown in Figure 4. Figure 4. Absorption spectrum of carbon dioxide (CO2). The available output range of IR sources and the absorption spectrum of water also govern the choice of the sensing wavelengths. Water shows strong absorptions below 3000 nm and also between 4500 nm and 8000 nm. Any attempt to sense gas ...

Measuring Atmospheric Carbon Dioxide at the South Pole ...

2010-07-26· The NIDR uses an infrared source which is a heated filament that emits infrared radiation around the same wavelength that carbon dioxide likes to absorb (usually around µm). This energy travels through two absorption cells, one of which is containing a sample of air from outside, and another that is containing a reference gas from a compressed gas cylinder. A mechanical chopper wheel ...

Infrared Measurement Principle (NDIR) - ecom

A non-dispersive infrared sensor is used in gas analysis to determine the gas concentration. NDIR analysers are particularly suitable for the determination of the concentration of carbon monoxide, carbon dioxide or hydrocarbons in a gas. Components of this process are a source of infrared radiation, an irradiated tube (cuvette) with the gas to be analysed, […]

Basic Principle of NDIR Gas Detection - Heimann Sensor

The basic measurement principle is called nondispersive infrared (NDIR) gas detection, which is based on the absorption of infrared radiation at certain gas specific wavelengths in accordance with the Beer-Lambert law. The most common gases that are measured with this NDIR principle are carbon dioxide (CO2), methane (CH4) and hydrocarbons (HC).

CO₂ sensor - Infineon Technologies

Poor ventilation can result in lower oxygen levels and a build-up of carbon dioxide (CO 2). Even moderate levels of CO 2 can have a negative impact on health and productivity. Already at 1000ppm, people begin to experience drowsiness and have difficulty concentrating. Consequently, there is a growing demand for smart indoor air quality sensors that can “smell” rising levels of CO 2 and ...

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 ...
