Carbon dioxide (CO ) measurement using Non-Dispersive ...

Non-Dispersive Infrared (NDIR) Spectroscopy . Non-Dispersive Infrared (NDIR) spectroscopy is a measurement technique used to non-invasively detect gas concentrations. Depending on their molecular composition, polyatomic gases possess the ability to absorb electromagnetic radiation at specific wavelengths in the infrared region. NDIR spectroscopy utilizes this ability to determine the measured gas

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 …
