NDIR is an industry term for " nondispersive infrared ", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector.
The 1Wire carbon dioxide sensor supplies precise measurement and stable performance. It can be used to measure a wide variety of CO₂ concentrations in public areas, offices, and industries. The sensor uses 1Wire interface for communication. Only one TCG200 can be connected to the 1Wire bus, but several another sensors can be connected too.
20210814· Adafruit SCD41 – NDIR CO2 Temperature and Humidity Sensor – STEMMA QT / Qwiic. The SCD41 is a photoacoustic ‘true’ CO2 sensor that will tell you the CO2 PPM (partspermillion) composition of ambient air. Unlike the SGP30, this sensor isn’t approximating it from VOC gas concentration – it really is measuring the CO2 concentration ...
NDIR stands for ''Non Dispersive InfraRed'' and it is s gas concentration measurement method that uses the unique absorption wavelength range of each gas. For example, CO2 absorbs infrared wavelength region of µm. Since amount of infrared which passes through the atmosphere depends on concentration of CO2 gas contained therein, it is ...

A basic NDIR sensor consists of an infrared light source, a sample chamber, an infrared filter, and infrared detector. For carbon dioxide sensing, room or duct air is allowed to flow in and out of the sample chamber. Infrared light waves are created by the source and sent through the sample chamber to the detector. As the infrared light passes through the air in the chamber, light of a ...
