how do carbon dioxide sensors work
The more CO2 present the more light the sensor will absorb. The short answer.
Electrochemical sensors also exist but these can be.
. NDIR sensors work by using specific wavelengths of light to measure the amount of CO2 in the air. Operation is simple. Consisting of two electrodes a working electrode.
Despite the fact that Carbon Dioxide is difficult to detect Edinburgh Sensors range of CO2 detectors allows for Carbon Dioxide measurement via the strong absorption of non. The target gas is determined through the. NDIR sensors work by using specific wavelengths of light to measure the amount of CO2 in the air.

The sensor in the form of a small box measures the level of carbon dioxide CO2 present in the air. NDIR CO2 sensors monitor and detect for the presence of carbon dioxide based on the absorption of infrared light at a specific wavelength. NDIR sensors are spectroscopic sensors that detect carbon dioxide in a gaseous environment by its characteristic absorption.
An NDIR sensor measures how much infrared light of a specific wavelength is absorbed by the surrounding air. Metal oxide semiconductor sensors use circuits applied to a silica chip. An NDIR sensor comprises an infrared source a light tube a bandpass filter and a detector.
