Low Cost IR CO2 Sensors -

This CO2 sensor module is designed to monitor 0-5,000ppm carbon dioxide levels using a dual beam light source and NDIR sensing technologies. By using the dual-infrared source principle, the CU-1107 sensor compensates for long-term 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 …

Infrared Technology for Hydrocarbon Gas Detection

IR detector that has been modified to be sensitive to the appropriate absorbing wavelength can also monitor gases other than hydrocarbons. An example of such detector is the IR7000 point IR detector, capable of measuring 0 to 5000 ppm of carbon dioxide. This instrument is derived from the standard IR2100 by using optics and filters suited to the μm absorption band of carbon dioxide. The …

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

26/07/2016· Higher CO2 levels would cause fewer IR rays to pass through the filter and be detected by the sensor. Low CO2 levels would cause more IR rays to be detected by the sensor. But the question still remains. Which one is better? If you examined carefully the abovementioned characteristics of TC and IR sensors, you would not disagree if we reach the conclusion that IR sensors are better than TC. …

Complete Gas Sensor Circuit Using Nondispersive Infrared …

If IR light is applied to a dual thermopile detector fitted with a pair of optical filters so that one filter is centered on 4260 nm and the other on 3910 nm, the concentration of carbon dioxide can be measured from the ratios of the two thermopile voltages. The optical filter that resides within the absorption channel serves as the detection channel and the optical filter that resides outside the absorption spectrum …
