How does an NDIR CO2 Sensor Work? |

Small NDIR CO2 sensor breakthrough. An engineering breakthrough occurred in 1993 when SenseAir AB patented a design for smallfootprint CO2 sensors. These sensors solved the size problem by using folded optics and metalized molded plastic to reflect the light through a curved shape (referred to as a ''waveguide'') that was longer than the footprint of the sensor module. The highly reflective coating …

CO2 sensor for use in water and atmosphere

Order a combi instrument including the CO2 sensor + our Oxygensensor and monitor CO2 and Oxygen together. This helps you to avoid and even reverse gill problems. Depending on the oxygen (O2) level, too much or too little carbondioxide (CO2) can cause problems for fish gills. If you have little O2, then you need a lot of CO2. If you have little CO2, then you need a lot of O2 to avoid problems ...

How do the sensor and CO2 sensor work? | AirVisual ...

2. How does the IR CO2 sensor work? The CO2 censor is composed of an infrared (IR) lamp, a reflective gas cell, and IR filtered detectors. The IR lamp sends waves of light towards the IR filtered detectors, which can measure how much IR light reach them. While the IR light goes through the cell, CO2 modules absorb lights of certain wavelength (shown in the graph). Thus, the number of CO2 …

What is a CO2 Sensor? | How does it work? CALT Sensor

How does it Work? An NDIR CO 2 sensor has 4 important parts, the chamber, gas inlet and outlet valve, infrared(IR) lamp, and an IR detector. One end of the chamber has an IR lamp that produces IR rays within the absorption band of CO 2 molecules. At the opposite end of the chamber, an IR detector is fixed to measure the intensity of the emitted rays. The inlet and outlet valves control the ...
