A simple CO2 sensing system was developed using an inexpensive nondispersive infrared (NDIR) CO2 sensor and was successfully deployed to differentiate the control and dieselcontaminated soils in terms of CO2 emission after glucose addition. Also, the sensor system distinguished glucoseinduced CO2 emission from sterile and control soil ...

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, a wavelength filter and an infrared detector. The gas which has to be analysed is pumped into the sample. To ensure the sensor ...

These NDIR CO2 sensors measure temperature, relative humidity and CO2. Carbon dioxide or CO2 is a result of human metabolism. Moderate to high levels of CO2 can cause headaches and fatigue. To prevent or reduce high concentrations of carbon dioxide in a building or room, fresh air should be supplied to the room.

NDIR Gas Sensors Electrical Optical Components, Inc.

+

An NDIR gas sensor (nondispersive infrared sensors) is a simple spectroscopic device often used as gas detector. It is called nondispersive because the wavelength which passes through the sampling chamber is not prefiltered. Instead a narrow bandpass (or NBP) filter is used before the detector. The NDIR sensor is a broadband IR detector using ...
