What Does a CO2 Sensor Actually Do? | GDS Corp

2020-11-06· CO2 sensors use the same operating principle as infrared hydrocarbon detectors. They create a beam of infrared light tuned to a specific frequency that is readily absorbed by CO2 molecules. The primary difference between an infrared CO2 detector and an infrared hydrocarbon detector is the choice of filter and infrared wavelength. Since each molecule of CO2 absorbed some of the infrared …

Go Direct® CO2 Gas Sensor User Manual – Vernier

Carbon dioxide gas moves in and out of the sensor tube by diffusion through the vent holes in the sensor tube. The sensor uses a small light to generate infrared radiation (IR). The IR source is located at one end of the sensor’s shaft. At the other end of the shaft is an infrared sensor that measures how much radiation gets through the sample without being absorbed by the carbon dioxide ...

Sensors - Gases PRO Sensor Guide - Libelium

Gas sensors (except the combustible gases sensor and the CO2 sensor) are electrochemical cells that operate in the amperometric mode. That is, they generate a current that is linearly proportional to the fractional volume of the target gas. These sensors are composed of 3 metal strips connecting each electrode to the three pins outside of the sensor body and a cell electrolyte. Each electrode ...
