Difference between single beam and dual beam CO2 sensor ...

NDIR CO2 Gas Sensor Introduction Gas with asymmetric molecular structure has strong absorption of infrared. So CO2 gas sensor NDIRbased has perfect selectivity for gas. Basically, the key components of the sensor are an infrared source, gas chamber and an infrared detector. When light wave corresponded to certain gas with absorption spectrum passes through measured gas, the intensity of …

Low Cost IR CO2 Sensors

This CO2 sensor module is designed to monitor 05,000ppm carbon dioxide levels using a dual beam light source and NDIR sensing technologies. By using the dualinfrared source principle, the CU1107 sensor compensates for longterm drifts by design. Dual beam detection allows for superior stability and better accuracy over the predicted 10 year lifespan of the sensor. It can achieve equivalent ...

IR vs TC: Settling the CO2 sensor debate once and for all ...

20160726· IR Sensors. IR sensors, on the other hand, operate on the theory that light is absorbed by gases at specific frequencies. For instance, light is absorbed by CO2 at μm, within the IR band of the electromagnetic spectrum. The sensor measures the IR light directed at the CO2 gas. Other wavelengths are prevented from hitting the sensor via a ...

Low Volt IR Co2 Sensors and Diving

20080325· Just curious, I was looking at Co2 Sensors, and I ran across several IR measuring Co2 Sensors with less then 1 sec response times, like this ICX Photonics manufactures IR gas sensors and emitters for Industrial Safety, IAQ and HVAC applications. and was wondering why something like this couldn''t be used in rebreathers? They suck low power (35mW), and either return ppm or %.

How does an NDIR CO2 Sensor Work? |

NDIR is an industry term for "nondispersive infrared", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector. The IR light detector measures the amount of IR light that passes through the optical filter. The band of IR ...
