Carbon Dioxide CO2 Sensor NDIR 1 PPM Resolution | …

20210609· NDIR stands for Non Dispersive Infrared radiation and the carbon dioxide (CO2) sensors are based on NDIR technology. This technique is widely used to detect carbonbased gases such as CO2 that are present in the air. The CO2 gas enters the sensor and light from the Infrared (IF) source falls on CO2 molecules. These molecules absorb some amount of light at a wavelength of µm. This ...


Sensors Gases PRO Sensor Guide Libelium

The IR series of infrared gas detection sensors use the technique of NDIR (NonDispersive Infrared) to monitor the presence of hydrocarbons or carbon dioxide. This technique is based on the fact that the gas has a unique and welldefined light absorption curve in the infrared spectrum that can be used to identify the specific gas. The gas concentration can be determined by using a suitable ...
