Modern NDIR CO2 sensors. Today''s newest generation of CO2 sensors has even more optimized waveguides, allowing a longer optical light path to be folded into an even smaller. 8 mm x 33 mm x 20 mm footprint. In addition to a smaller size, new midrange infrared lightemitting diode (LED) light sources have been developed that allow NDIR …
NDIR sensors for carbon dioxide are often encountered in heating, ventilation, and air conditioning (HVAC) units. Configurations with multiple filters, either on individual sensors or on a rotating wheel, allow simultaneous measurement at several chosen wavelengths.
This article describes a circuit that is a complete thermopilebased gas sensor using the NDIR principle. This circuit is optimized for CO2 sensing, but can also accurately measure the concentration of a large number of gases by using thermopiles with different optical filters.
The CO2 sensor chosen here is an infrared NDIR CO2 sensor made by Gravity. Several other models exist on the market, although most are more expensive than this one. This particular model provides an analog output with a tension varying from 0 to 2V. This output is connected to pin A2 on the board. That pin is used as an analog input, and an instruction in the code activates its 12bit ADC ...

· comparing NDIR sensors with two commonly applied methods, a PhotoAcoustic Spectroscope (PAS) Gas Monitor and an OpenPath laser (OPlaser). First, calibrations for the NDIR sensors were obtained in the laboratory. Then, the NDIR sensors were placed in a dairy cow barn for comparison with the PAS and OPlaser methods. The main conclusions were: (a) in order to represent the overall barn CO2 ...
