The basic measurement principle is called nondispersive infrared (NDIR) gas detection, which is based on the absorption of infrared radiation at certain gas specific wavelengths in accordance with the Beer-Lambert law. The most common gases that are measured with this NDIR principle are carbon dioxide (CO2), methane (CH4) and hydrocarbons (HC).
SSG11DF42G1 NDIR Infrared CO2 gas sensor is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, non-oxygen dependent and long life. Built-in temperature sensor can do temperature compensation; and it has digital output and analog voltage output.

devices were not available for utilization in NDIR gas sensors until the late 1950’s. • The first ever NDIR gas sensor for sale was the Beckman LB-I medical CO 2 analyzer in the early 1960’s for measuring end-tidal CO 2 levels for cardiac patients in hospital ICUs. • The Beckman LB-I was single-beam designed having a DC-operated
Aug 21, 2019· Overcome the disadvantages using NDIR CO2 sensor. These shortages of the chemical sensor can be solved by using an NDIR CO2 sensor, An IR transmitter trains a special wave of light through a tube filled with sample air toward an optical filter in front of an IR light sensor. The IR light sensor measures the amount of IR light that passes ...

Jun 15, 2018· The most common solutions for monitoring indoor CO2 levels are non-dispersive infrared (NDIR) CO2 sensors. In an NDIR CO2 sensor, infrared light is conveyed through a tube of air to an infrared detector. The detector recognizes the light that was not absorbed by the CO2 present in the tube, and the concentration of atmospheric CO2 is measured.
In continuous operation ExplorIR® NDIR CO₂ sensor delivers two samples/second and consumes only in continuous operation. Even with two carbon dioxide measurements per second delivering low latency and accurate results, it is typically 50 times lower powered than standard NDIR …
