Complete Gas Sensor Circuit Using Nondispersive Infrared ...

+

Nondispersive infrared (NDIR) spectroscopy is often used to detect gas and measure the concentration of carbon oxides (for example, carbon monoxide and carbon dioxide). An infrared beam passes through the sampling chamber, and each gas component in the sample absorbs some particular frequency of infrared. By measuring the amount of absorbed infrared at the appropriate frequency, the ...

In contrast, NDIR sensors offer longterm stability, high accuracy and high gas specificity [17], and this method is more favorable compared to electrochemical sensors as CO2 is an inert gas and has minimal electrochemical response. Typically, NDIR CO2 sensors use the strong absorption of CO2 around m, a wavelength range where no other common molecules absorb, thereby avoiding cross ...

NDIR Sensor for NonDispersive Infrared Detection

+

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 systems and are the systems of choice. Eliminating ...

Schematic diagram of NDIR gas sensor. Given that pyroelectric detectors react to fluctuations in light level, the IR source had to be modulated. At 1 to 10Hz pulse rate, the detectors’ output is sinusoidal with a peaktopeak AC voltage proportional to the intensity of the IR incident on the detector. In case an IRabsorbent gas enters the cell, the IR intensity on the active detector will ...
