CO2 Gas Sensor User Manual – Vernier

The Vernier CO 2 Gas Sensor measures gaseous carbon dioxide levels in the range of 0 to 10,000 ppm (Low range setting) or 0 to 100,000 ppm (High range setting) by monitoring the amount of infrared radiation absorbed by carbon dioxide molecules. Carbon dioxide gas moves in and out of the sensor tube by diffusion through the twenty vent holes in the sensor tube. The sensor uses a small …

Carbon Dioxide Sensor Sensor Technology | Sensors ...

NDIR sensors are spectroscopic sensors that detect carbon dioxide in a gaseous environment by its characteristic absorption. It includes an infrared detector, an interference filter, a light tube and an infrared source. The gas is either pumped or diffused into the light tube, and the electronics measure the absorption of the wavelength of light. Chemical Carbon Dioxide Sensors. Chemical ...

COVER STORY 2 Sensor Helps to Reduce the Risk of Covid19 ...

The various indoor pollutants can also be detected by the socalled eCO 2 sensors, but unlike the NDIR sensor, they do not perform real measurements. Instead, they use algorithms to calculate an equivalent CO 2 value. These sensors deliver estimated values based on many assumptions, such as how many people — as the cause of an increasing CO 2

Basic Principle of NDIR Gas Detection Heimann Sensor

The picture below illustrates the principle using the example of a NDIR CO2 sensor: On the right side we have an IR light source that emits radiation at all wavelengths. The reflector is used to direct as much light as possible in the direction of the thermopile detector which is on the left side. In between there is a tube with IR reflecting walls which is used as measurement path. For CO2 ...
