Prana Air CO 2 sensor is based on NDIR (Non Dispersive Infrared radiation) technology. This technique is widely used to detect carbon based gases that are present in air. The absorption wavelength of carbon dioxide in this technology is um. The infrared radiation is passed through the carbon dioxide gas when it hits the sensor surface.
A carbon dioxide sensor or CO2 sensor is an instrument for the measurement of carbon dioxide gas. The most common principles for CO 2 sensors are infrared gas sensors ( NDIR) and chemical gas sensors. Measuring carbon dioxide is important in monitoring indoor air quality, the function of the lungs in the form of a capnograph device, and many ...

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.
is used to detect the amount of a specific gas. For instance, since CO2 has a strong absorbance at a wavelength of µm, a bandpassfilter is used to remove all light outside of this wavelength. Figure below shows the basic NDIR gas sensor working principle. Figure 1. NDIR Gas Sensor Principle
