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 gasspecific narrow band optical filter.

Adafruit SCD30 NDIR CO2 Temperature and Humidity Sensor

20210725· The SCD30 is an NDIR sensor, which is a ''true'' CO2 sensor, that will tell you the CO2 PPM (partspermillion) 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 ...

Catalytic Gas Detector: How Catalytic Bead Sensors Work ...

20171002· A portable gas detector with the NDIR combustible gas sensor requires up to 5 minutes warmup time after it has been turned on before the sensor readings become accurate. In addition, NDIR sensors are 34 times more expensive than catalytic bead sensors. The advantage of using NDIR sensors is that they are not affected by contaminants, do not require oxygen, and use less power.
