Signal conditioning for NDIR sensor - Application note

In the case of an NDIR CO. 2. sensor, the active channel is combined with a filter which allows the µm wavelength to pass, that is the quantity the CO. 2. molecule can absorb. The reference channel has a filter centered on µm where there is no absorption as described by (data are issued by HITRAN database). Figure 3. Absorption spectrum of CO. 2. Absorption spectrum of CO2 0 ...

Basic Principle of NDIR Gas Detection - Heimann Sensor

The picture below illustrates the principle using the example of a NDIR CO2 sensor: On the right side we have an IR light source that emits radiation at all wavelengths. The reflector is used to direct as much light as possible in the direction of the thermopile detector which is on the left side. In between there is a tube with IR reflecting walls which is used as measurement path. For CO2 ...

Adafruit SCD-30 - NDIR CO2 Temperature and Humidity Sensor

· The SCD-30 is an NDIR sensor (https:///CQ6), 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 (https:///PF7) - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect ...
