Messung von CO2 mittels NDIR-Sensoren

· Kohlendioxid (CO2) in Luft wird normalerweise in Teilen pro Million (ppm) gemessen. Bei ppm CO2 würde eine Million Luftmoleküle eine Mischung aus Luftmolekülen und CO2-Molekülen enthalten. Die gebräuchlichsten CO2-Sensoren sind unter dem Begriff Non-Dispersive InfaRed oder NDIR bekannt. Ein NDIR-CO2-Sensor strahlt Infrarotlicht durch eine Gasprobe in einer …

Adafruit SCD-30 - NDIR CO2 Temperature and Humidity Sensor

· The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...

Luftqualität mit NDIR- und MOX-Sensoren messen – ckArduino

· NDIR-Sensoren (nicht-dispersive Infrarotsensoren) nutzen die konzentrationsabhängige Absorption elektromagnetischer Strahlung im Infrarot-Bereich. Bei einer Wellenlänge von um liegt eine maximale Absorption von CO₂, ohne große Beeinflussung durch andere Gase. Die CO₂-Konzentration kann deshalb sehr selektiv gemessen werden. Das Umweltbundesamt (UBA) empfiehlt …

Basic Principle of NDIR Gas Detection - Heimann Sensor

NDIR Gas Measurement Principle. To measure the gas concentration with precision, you need two thermopile sensors and an infrared light source. One sensor serves as reference to monitor the variation of IR source output due to source aging, power variations, etc.. The other sensor is equipped with a gas-specific narrow band optical filter.
