Infrared co2 sensor electronic component . MHZ16 NDIR Infrared gas module is a common type, small size sensor, using nondispersive . infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, nonoxygen dependant, long life.
NDIR CO2 sensors take a new reading anywhere from 20 times a second to once every 30 seconds. As each reading is taken the sensor''s onboard software takes into account all the previous measurements and report the average. This solves the problem of precision. If you want a more precise CO2 reading, look for a sensor with a higher frequency of ...

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is nondispersive in the fact that no dispersive element ( a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.
In this paper, we propose a novel, miniaturized nondispersive infrared (NDIR) CO2 sensor implemented on a silicon chip. The sensor has a simple structure, consisting of a hollow metallic cylindrical cavity along with access waveguides. A detailed analysis of the proposed sensor is presented. Simulation with 3D ray tracing shows that an integrating cylinder with 4 mm diameter gives an ...

This is a nondispersive infrared (NDIR) approach. It has been shown (Jacquinot P. 1954 J. Opt. Soc. Amer. 44, 761765) that optical filters are typically 1000 times more efficient than gratings and up to 100,000 times more efficient than prisms at separating IR wavelengths, so NDIR gas sensors offer real performance advantages over dispersive ...

Jun 09, 2021· NDIR CO2 Sensor. Nondispersive infrared, often called NDIR, sensors deliver high accuracy and fast response time. NDIR sensors have no contact with the gas, making them more reliable, and are constructed for specific gases so that they are unaffected by other gases. NDIR sensors are the most reliable method for detecting carbon dioxide gas.
