How UV, IR and Imaging Detectors Work - Sensor Technology

The IR sensor is curbed to keep a “reasonable” activation of the IR chain by the surrounding thermal background. By using extra information in the IR band, via a second sensor, this increases the gain of the amplification chains of the detector and thus increases the detection range, and at the same time maintains a good immunity to false alarms.

Thermal Conductivity versus Infrared CO2 Sensors | Blog ...

2018-10-06· The CO2Cell Incubator and the SCO Air Jacket CO2 Incubator both utilize IR sensors. The sensor can detect how much CO 2 is in the atmosphere by measuring how much μm light passes through it. The big difference here is that the amount of light detected is not dependent on any other factors, such as temperature and humidity, as is the case with thermal resistance.

Carbon Dioxide Sensor - Sensor Technology | Sensors ...

The IR light detector measures the amount of IR light that passes through the optical filter. The band of IR radiation produced by the lamp is very close to the absorption band of CO2. Because the IR spectrum of CO2 is unique, matching the light source wavelength serves as a signature or "fingerprint" to identify the CO2 molecule.
