inkl. 19% MwSt.
zzgl. Versandkosten





NDIR  CO2 Sensor (nichtdispersiver Infrarotsensor) . Dieser Sensor misst den CO2 Gehalt über das Ausmaß Absorption von Infrarotlicht einer bestimmten Wellenlänge. Die rein optische Messung hat den Vorteil dass sie kaum einem Verschleiss aufweist, also die Lebensdauer gegenüber Sensoren die auf chemischer Reaktion beruhen höher ist. Auch die Reaktionzeit ist kürzer und der Sensor ist unempfindlicher gegenüber Umwelteinflüsse (z.B. Feuchtigkeit)

Kohlendioxid (CO2) ist ein wichtiger Indikator for die Qualität von Raumluft, bei zu hohen Werten leidet Konzentration, Aufmerksamkeit und Denkvermögen. Ein Wert von unter 1000ppm ist anzustreben . Mit diesem Sensor lassen sich Messgeräte zur Beurteilung/Monitoring  der Luftqualität in Innenräumen z.b. in Klassenräumen, Büro, Arbeitsplatz aufbauen oder Steuerungen von Lüftungsanlagen etc.         




The concentration of carbon dioxide (0.03% usuallly) is related to daily life. Recently, there’s a study showing that the atmospheric CO2 content has reached 0.0385% (385 ppm) which is the highest value since 2.1 million years. The raise of atmospheric CO2 content to some extent results in global climate change. How to accurately measure the carbon dioxide gas concentration is becoming a universal research topic.

DFRobot released its latest high-precision analog infrared CO2 sensor. The effectively measuring range is from 0 to 5000ppm. This sensor is based on non-dispersive infrared (NDIR) technology and has good selectivity and oxygen-free dependency. Besides, its service life could up to 5 years! It integrates temperature compensation and support DAC output. Most importantly, the product is easy to use; it is compatible with all types of microcontrollers such as Arduino with ADC function.

In addition, this product is a high-performance sensor that combines technology of mature infrared absorption gas detection with precision optical circuit design as well as sophisticated circuit design. It has characteristics such as high sensitivity, high resolution, low power consumption, fast response, anti-water vapor interference, no poisoning, high stability and long life.

This sensor is able to directly compatible with the DFRobot Arduino IO expansion board thanks to its external DFRobot Gravity interface. This character simplify the use of the sensor as it is plug and play and no need additional wiring.

This product could be widely used in HVAC, indoor air quality monitoring, industrial process and security protection monitoring, agriculture and animal husbandry production process monitoring.
