Introduction to Gas Sensing Using Non-Dispersive Infrared ...

Carbon-dioxide infrared spectrum. Figure 3. Methane infrared spectrum . IR reacts with the gas only when a dipole on the molecule is created. Molecular dipoles can occur when the vibration modes are non-symmetrical or when atoms in the molecules are organized in a non-symmetrical fashion. The vibrations comprise bending and stretching of the molecules that deform them to produce dipole or ...

Remote Sensors | Earthdata

· Remote sensing instruments are of two primary types: Active sensors, provide their own source of energy to illuminate the objects they observe. An active sensor emits radiation in the direction of the target to be investigated. The sensor then detects and measures the radiation that is reflected or backscattered from the target.

Infrarotabsorption in CO2 (Treibhauseffekt)

• Bei unserem IR-Detektor handelt es sich um einen pyroelektrischen Detektor. Das Kristallgitter eines pyroelektrischen Materials besteht aus zwei Untergittern, die jeweils mit positiven und negativen Ionen besetzt sind. Die Absorption eines IR-Photons führt zu einer lokalen Verformung des Gitters, wodurch sich die Abstände zwischen positiven und

CO2 Sensors vs. VOC Sensors for IAQ - What's the ...

Most IR carbon dioxide sensors only measure CO2. A CO2 sensor is designed to control the ventilation rate in occupied spaces. People are the principal source of CO2 in indoor air. Whereas outside air carbon dioxide levels tend to be relatively low and constant, an indoor CO2 measurement can be used to determine whether a room or building is occupied. In other words, higher levels of CO2 …
